ITEM NAME:HTU21D Temperature And Humidity Sensor Module Upgrade D2L5 HTU21D Temperature And Humidity Sensor Module Upgrade D2L5 Based on high-performance humidity sensing elements are made of a new generation HTU21D temperature and humidity sensors based on size and intelligence of the new standards: it is embedded in a reflow solderable Dual Flat No leads (DFN) Sensor output signal digitally calibrated, standard I2C format. Diversification of output, wide operating voltage range, and has a high precision temperature and humidity accuracy. HTU21 series modules are designed for low-power small size application design, with good quality, fast response, anti-interference ability and cost advantages, very low power consumption. Temperature measurement range: -40 Celsius ~ 105 Celsius ; humidity accuracy range (10% RH to 95% RH): HTU21D +/- 2% RH; Humidity Hysteresis: +/- 1% RH; measuring time: 50ms; annual shift: -0.5% RH / year. Supply voltage: 1.5V-3.6 Maximum power consumption: 2.7uW Of communication: I2C Response time: 5 s Weight:0.9g Size:3*3*1.1cm(L*W*H) Material:Metal color:red Package Contents: 1x sensor module Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
