The CWS28 outdoor humidity and temperature transmitter is a comprehensive transmitter that integrates temperature, humidity and barometric pressure sensors. CWS28 outdoor integrated transmitter of temperature, humidity and atmospheric pressure is widely used in various meteorological monitoring, outdoor environment temperature, humidity and atmospheric pressure measurement. The sensor of CWS28 outdoor integrated transmitter with temperature, humidity and atmospheric pressure adopts a high-precision temperature and humidity integrated chip. The temperature is measured by using the P-N junction of the diode, and the forward voltage drop varies with the temperature under the constant current. Humidity is measured by the characteristics of moisture-sensitive capacitance, which changes with the change of humidity and capacitance value. Temperature and humidity compensate for each other. The atmospheric pressure is the diffusion of a Wheatstone bridge on a monocrystalline silicon wafer, and the pressure exerted by the measured medium causes the resistance value of the bridge wall to change (piezoresistive effect). The amplification circuit then amplifies the digital signal into the corresponding wet temperature and atmospheric pressure standards. CWS28 outdoor integrated transmitter with temperature, humidity and atmospheric pressure has the following features: First of all, the sensor operates in a wide temperature range (-40°C~85°C) Secondly, low drift and fast response Third, the special material design prevents sunlight radiation and rain, and the height can be increased or decreased at will Fourth, high precision, easy installation and stable performance Fifth, it has a long service life and strong anti-interference ability Sixth, wide voltage power supply and nonlinear correction Seventh, wiring reverse and overvoltage protection and current limit protection If you have any questions about product consultation, product customization, agency, technical inquiry, quotation, etc., please contact Xingyi, 400-600-4496!
