Product introduction] Temperature and Humidity module RHI-112A long experience to develop the humidity sensor drive circuit dedicated module, easy to use, and achieve a low price to provide high-precision humidity detection possibilities. It has the characteristics of high precision, small temperature dependence and the control of single chip microcomputer in the world, so there is no need to correct the temperature and humidity detection range. This product is produced in Japan Shen Rong Co., Ltd.
[Electrical parameters] Rated voltage: DC3.15 ~ 5.5 V Rated power: 0.5mA (MAX, sine wave) Usage Temperature range: 0~60° Humidity detection range: 10 to 90 % RH Storage Temperature range:-20~70° Save humidity range: 95 % below RH(no condensation) Precision of humidity detection: +3% RH

[Standard Test Conditions] In the atmosphere, the temperature is 25 °, the frequency is 1KHz, and the voltage 1VAC (sine wave) is used as the standard. Characteristic test, first put the humidity sensor into the dry air of 25°/0%RH, wait 30 minutes, and then set the humidity to 60%RH, and then wait 15 minutes, test the resistance value. Measuring device: Shunt humidity Generator: SPH-1 type (Divine Rong System)
[Notes] A Do not let the product condensation, and do not let the product dip. B Do not use in the following gas environments: salt, inorganic gases (sulfur dioxide, chlorine, Ammonia), organic gases (alcohol, ethylene glycol ether, aldehydes) C. It is best not to keep it in an environment above 60 °C for a long time, as this will easily deform the sensor protection box
