BW-8 series switch intelligent control device adopts a new integrated digital temperature and humidity sensor, universality and interchangeability of the sensor is very good, without the need for sensor calibration human can achieve high accuracy of measurement, and, because of the one-piece sensors is temperature and humidity, which can achieve high precision of leakage measurement. The device CPU uses ATMEL company's high performance, low power consumption ATMEL64 microcontroller. Rich resources, fast computing speed, strong anti-interference ability, stable and reliable operation.
