Temperature and humidity sensor for remote monitoring
When you are on a business trip or out of town, the ability to monitor the temperature and humidity of your home, warehouse, or cold storage is essential. Temperatures that are too high or too low can cause costly losses. Therefore, an alarm from a remote wifi temperature humidity sensor will enable you to take precautions before the temperature or humidity reaches destructive levels.
Do you want to have a temperature and humidity detector that can remotely monitor every room or every corner? This kind of temperature and humidity sensor can not only send alarm information in real-time but also monitor the temperature and humidity conditions of all places through mobile phones. It can use the backup battery to supply power when the power is off, and it can ensure that the power-off process can also be continuously monitored.In this article, we will tell you in detail how to remotely monitor temperature through a mobile phone or computer, and recommend the best function of wifi temperature and humidity sensor.
What is a wifi temperature humidity sensor?
The WiFi temperature humidity sensor measures the temperature and humidity of the surrounding environment by a built-in sensor module, and wirelessly sends the information to the Internet through a WIFI connection. Depending on the type of temperature sensor, you can use software, mobile applications, computer browsers, or any combination of the three to view data on the PC.
To build a complete remote monitoring temperature and humidity system, you need to prepare the following conditions:
1. Install stable wifi in the place you need to measure (such as home, office, warehouse, etc.)
2. A certain number of wifi temperature and humidity sensors
3. The same number of power adapters as the sensor
4. Install the corresponding platform or small program on your computer and mobile phone to monitor
Features of remote WiFi temperature humidity sensor:
1. Wireless transmission
Signal transmission via wifi is not limited by distance, and the cost is low. You only need to install a stable router in your home, office, or other locations that need to be monitored. Ensure that the wifi temperature humidity sensor can upload data normally. Avoid the distance limitation of transmitting information via Bluetooth. Even if you stay away from the monitoring site for a long time, you can ensure long-term stable temperature and humidity monitoring.At present, most of the wifi sensors on the market do not have the built-in wifi function and need to be attached to the router (wifi hotspot) in the current environment to work normally.
2. The data upload interval can be customized
The update interval or frequency is how often the temperature sensor sends data to the WiFi network so that you can check it on your computer or mobile phone.
The data upload interval of the high-precision wifi temperature and humidity sensor is the 20S/time by default, and 1S~10000S can be set freely. It takes a long time to upload data of ordinary precision temperature sensors, and you need to update it every 5 minutes or less. Most sensors are updated every few minutes. You can set the appropriate update frequency according to your needs, because this may be a trade-off for extending battery life.
3. Data sharing
You can set up multiple sub-accounts through the mobile app so that your colleagues or family members can also share data. Once a temperature sensor detects an abnormality in the current environment, the shared account can also receive alarm information at the same time.
There is no requirement for the number of shared accounts. You can set it according to your needs. Log in to the mobile app and create a new account and set the new account permissions. Then you can share one or more sensors with your family or colleagues.
4. Data is intuitive and clear
Through the excellent smart phone app, you can view the current temperature and humidity value and historical data of a certain sensor in a specific location, and you can also view the measurement value and historical data of multiple temperature humidity sensors at the same time. The line graph can intuitively reflect the changes in temperature and humidity throughout the day.
For example, you can see the lows and highs of the temperature and the time of day in the chart below. This can help you find problems that are causing high or low temperatures in the area you are monitoring.
5. With data logging function
If the WiFi signal is lost or out of range, the sensor can also record temperature and humidity data. Once WiFi is restored, it can automatically connect and upload the recorded data. The advantage of having this feature is that it allows you to record the temperature at a remote location (away from any WiFi), and you can even use the mobile hotspot of your phone to retrieve data at any time.
When setting up a new WiFi temperature sensor, simply add the phone’s hotspot to the WiFi profile. The best recording time for the temperature and humidity sensor is a measurement or sampling every 1 or 2 minutes.
6. Backup battery power supply
The wifi temperature and humidity sensor have two power supply methods, built-in battery power supply, or city power supply. Some temperature and humidity sensors on the market have these two power supply methods. The advantage of this function is that in the event of a sudden power failure, the device can automatically activate a backup battery to supply power. Avoid measurement interruption caused by power failure.
Normally, a backup battery can provide continuous power for the device for up to 6 hours, and the battery is rechargeable. Once the power is restored, the backup battery will be fully charged and continue to be backed up.
7. Long battery life
WiFi temperature and humidity sensor with two power supply modes, the service life of the built-in battery depends on the frequency of power failure, if the frequency of power failure is not high, the battery can work normally for 3-5 years. Battery life also depends on the distance between the Wi-Fi temperature sensor and your wireless home router and its update interval.
Using a fully built-in battery-powered Wi-Fi temperature sensor, with an update frequency of 4-5 minutes, the usual battery life should be about 6 months. Some Wi-Fi temperature sensors that are only updated once an hour, the battery can be used for 1 year or more. If there is a problem with the Wi-Fi router or a power failure needs to be notified in time, this is not frequent enough.
8. Multiple alarms
When the best wifi temperature and humidity sensor detects an abnormal temperature, it will sound at the same time, the alarm light flashes and send an alarm message to remind the user. Not only remind remote users but also remind users of the current environment to take measures.
In addition to abnormal temperature, when the equipment is not working properly (such as equipment power failure, signal loss, etc.), it will also send information to the user to remind the user to check the sensor and make adjustments in time.
9. Multi-channel data viewing
A good remote temperature sensor should include an application for mobile phones and desktop browsers. The app should allow you to view all data on temperature, humidity (if equipped), and battery level. Multiple temperature sensors can be monitored from the same mobile application at the same time.
You can set alarms for high or low-temperature levels. You can also set the recording time of the device according to your current location.
10. Optional multiple probes
Some wifi temperature and humidity sensors can be replaced according to different places of use. For example, if you want to measure the temperature and humidity of the ordinary atmosphere, you can choose a common built-in probe. If you want to measure the temperature and humidity in the water, you can choose an external waterproof probe. If you want to measure the cold storage can choose an external ultra-low temperature probe, if you want to measure the temperature and humidity data of multiple adjacent freezers at the same time, you can choose a multi-channel temperature and humidity sensor and so on.
11. Digital display function
In order to facilitate remote users and different users in the current environment can be prepared to master the temperature and humidity values, many wifi temperature sensors come with LCD display, users in the current environment can intuitively read the current temperature and humidity data through the LCD, avoiding the trouble of logging in to the platform. At the same time, the parameters can be adjusted through the buttons of the device. The two control methods are more convenient and faster.
