Features: Advanced Monitoring: The 3-in-1 CO2 Monitor is equipped with a state-of-the-art 2CH NDIR sensor for accurate and reliable carbon dioxide detection. It also Features a 2.4G WiFi connection and a large 7-inch LCD display, allowing you to easily monitor temperature, humidity, and CO2 levels in your greenhouse. Convenient Control: With the Tuya APP, you can remotely control and monitor your greenhouse environment from anywhere. The app allows you to switch between Celsius and Fahrenheit, set temperature and humidity thresholds, and even control the relay for devices such as dehumidifiers(not for humidifier), CO2 generators, air conditioners, fans, and more by the smart plug (the devices …

Feature: 1. High sensitivity, accurately identify the movement of biological and non-biological, minimized the rate of false identification. 2. Using 5.8GHz working frequency, strong anti-interference, stable and reliable performance. 3. Automatically identify the intensity of the ambient light, when meet the lighting requirements and someone passing, the light will on, otherwise it is off. 4. Adjustable dip-switch, the sensing distance, sensing time and light control brightness can be adjusted. 5. When someone enters the induction zone, and meets the lighting requirements, the switch automatically turns on and starts the delay system. As long as the human body does not leave the induction zone,…
