It can detect soil moisture and temperature, Indoor temperature and humidity. This series of products uses a highly integrated temperature and humidity sensor chip, the chip's full-scale calibration digital output. Its patented CMOSens technology ensures high reliability and long-term stability. The sensor consists of a capacitive polymer humidity sensor and a temperature sensitive component made of an energy gap material. The two components are designed on the same chip as a 14-bit A/D converter and a serial interface circuit. The sensor has excellent quality, ultra-fast response, strong anti-interference ability and high cost performance. Each sensor chip is calibrated in an extremely precise thermostatic chamber, referenced to a mirror condensing dew point meter. The calibration coefficients obtained by calibration are stored in the OTP memory of the chip itself in program form. The two-wire serial interface and internal voltage adjustment make peripheral system integration fast and simple.It includes light sensor, co2, wind speed sensor, outdoor temperature and humidity, rain and snow sensor, rainfall sensor.
