Product Description
| 【Product Introduction】 RHI-112A Temperature and humidity module is a dedicated module for humidity sensor drive circuit developed based on long-term experience. It is easy to use and can provide high-precision humidity detection at a low price. It has the characteristics of high accuracy, low temperature dependence, single-chip control so no need to correct temperature, and wide humidity detection range. |
| [Electrical parameters] Rated voltage: DC3.15~5.5V Rated power: 0.5mA (MAX, sine wave) Using temperature range: 0~60℃ Humidity detection range: 10~90%RH Storage temperature range: -20~70℃ Storage humidity range: below 95%RH (no condensation) Humidity detection accuracy: ±3%RH |
| 【Standard measurement conditions】 In the atmosphere, the temperature is 25℃, the frequency is 1KHZ, and the measurement voltage is 1VAC (sine wave) as the standard. When testing the characteristics, first put the humidity sensor in dry air at 25℃/0%RH, wait for 30 minutes, then set the humidity to 60%RH, wait for another 15 minutes, and then test the resistance value. Measurement device: Shunt-type humidity generator: SPH-1 type (made by Shinei) |
| 【Precautions】 A. Do not allow the product to condense or get wet. B. Do not use in an environment with the following gases: salt, inorganic gases (sulfur dioxide, chlorine, ammonia), organic gases (alcohols, glycol ethers, aldehydes) C. It is best not to store it in an environment above 60°C for a long time, as this will easily cause the sensor protection box to deform. |
