[Tuya Smart] Remote temperature and humidity sensor controller

1. Monitor the temperature and humidity of the current environment through the onboard temperature sensor.
2. Photoelectric solid-state relays are used to establish 4 external equipment control channels, which can control 110V/220V equipment, support a maximum current of 1.2A, and provide control status indicators.
3. Onboard SPI flash chip can be used for OTA online upgrade and data storage functions.
4. It has one-key on and off function.
5. The onboard lithium battery interface has lithium battery charging management and battery power monitoring functions.
6. Equipped with 3-way RGB operating status indicators.

Application scenarios:

• smart farm

It is used to monitor the temperature and humidity control of vegetable greenhouses. It obtains real-time temperature and humidity data of the greenhouse through the onboard temperature and humidity sensor. On the one hand, the MCU can be used to upload the acquired real-time data to the management center through the wifi module for background data analysis. On the other hand, a closed-loop control logic can be established in the MCU and controlled by 4 external devices to achieve a constant temperature and humidity value set in the greenhouse.

The same machine remotely controls multiple greenhouses in real time.

• smart home

By obtaining the temperature and humidity values, control air conditioners, dehumidifiers, humidifiers and other equipment.

• Intelligent transformation of traditional equipment, such as old-fashioned high and low temperature aging boxes, enables intelligent operations such as unmanned control and remote control.
