The ultra-low power series temperature and humidity transmitters launched by Shenzhen Yuanjian Sensing Technology Co., Ltd. have an average power consumption of less than 0.02W, which is more than 10 times lower than similar products. Ultra low power consumption and unique air duct design completely solve the problem of circuit board temperature rise, with more accurate measurement and faster response characteristics. The use of Swiss second-generation imported sensor probes ensures excellent measurement performance of the product. The product has powerful functions and stable performance, with multiple analog and digital signal outputs, and can be selected as one or two sets of solid-state relay outputs. With unique control logic, it can achieve any functional control and remote control, such as high temperature alarm, low temperature alarm, high humidity alarm, low humidity alarm, heating, cooling, humidification, dehumidification, etc, We can also accept customized development from customers.
