描述
Grove – Temperature&Humidity Sensor Pro(AM2302) 溫濕度感測器
Grove – Temperature&Humidity Sensor Pro(AM2302) 溫濕度感測器的檢測範圍為5%RH – 99%RH,-40°C – 80°C。其精度達到2%RH和0.5°C。對需求相對嚴格的應用程序的專業選擇。
本產品是家庭使用的高精度溫濕度傳感器。它由用於測量相對濕度的電容式傳感器元件和用於測量溫度的負溫度係數(NTC)熱敏電阻器組成。每個傳感器都在精確的濕度室內進行校準。超小尺寸,超低功耗,超過20米的信號傳輸距離使其成為各種應用環境的良好選擇。與Twig – Temp&Humi傳感器v0.9b不同的是,該模組的精度可以達到0.3度,相對濕度為2%。

Grove – Temperature&Humidity Sensor Pro(AM2302)
This product is a high accuracy temperature and humidity sensor used in home conditions. It consists of a capacitive sensor element used for measuring relative humidity and a negative temperature coefficient (NTC) thermistor used for measuring temperature. Every sensor was calibrated in an accurate humidity room. Small dimension, ultra low power consumption, more than 20m’s signal transmission distance make it a good selection for various application environment. Different from Twig – Temp&Humi Sensor v0.9b, the accuracy of this module can gets up to 0.3 degree in temperature and 2% in relative humidity.
