[Tuya Smart] Temperature and humidity sensor based on Tuya Smart

Overview

Zero code temperature and humidity sensor_WiFi

Module selection:

The XR3 module is a low-power embedded Wi-Fi module developed by Hangzhou Tuya Technology Co., Ltd. It consists of a highly integrated wireless radio frequency chip XR809 and a small number of peripheral devices. It has a built-in Wi-Fi network protocol stack and rich library functions. XR3 has built-in ARM Cortex-M4F CPU, 2Mbyte Flash Rom, 384KB SRAM and rich peripheral resources. Users can develop embedded Wi-Fi products that meet their own needs based on these.

Functional realization: It can help traditional temperature and humidity products to quickly connect to mobile apps, use temperature and humidity integrated sensors to regularly detect temperature and humidity data in the environment. Through the App, users can view device data anytime and anywhere, and can regularly detect battery power and battery It can push a message to notify the user when the battery is out, and can also set the temperature and appropriate range, which is convenient and fast.

In the hot summer, users only need to pre-set a certain temperature in the App to automatically turn on or off the air conditioner, and then the air conditioner can be linked to automatically sense the ambient temperature. When the temperature and humidity sensor detects that the indoor temperature is higher than 29°C, the air conditioner is turned on in a linkage manner; when the indoor temperature drops below 23°C, the air conditioner is turned off in a linkage manner. The entire process occurs seamlessly, saving worry and energy, keeping the temperature within a comfortable range. , which greatly facilitates our lives.

characteristic

Main frequency supports 160MHz
Working voltage: 2.7V-5.5V
Supports both SmartConfig and AP network configuration methods (including Android and IOS devices)
Onboard PCB antenna
Working temperature: -20℃ to 85℃

Using Tuya Smart’s development-free solution, 0 code is convenient and fast .

After pressing the button for 5 seconds, the indicator light flashes to enter the network distribution mode;
After the network configuration is successful, the indicator light goes out, and the button is used to synchronize the current temperature and humidity during normal use;
The power consumption during network distribution is 40ma, the synchronization data is about 20ma, the standby current is less than 1ma, and it can be powered by a button battery for a short period of time;
Using a SHT30 high-precision sensor
Working temperature and humidity range: 5℃～60℃ 20%RH～80%RH

Working voltage: 2.4～5.5V

Humidity measurement range: 0～100%RH

Humidity accuracy error: ±3%RH

Resolution: 0.01%RH

Response time: 8s

Temperature measurement range: -40℃~125℃ Accuracy error: ±0.3℃ Resolution: 0.015℃

Long-term drift: <0.03℃/year
