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.
This Temperature&Humidity sensor provides a pre-calibrated digital output. A unique capacitive sensor element measures relative humidity and the temperature is measured by a negative temperature coefficient (NTC) thermistor. It has excellent reliability and long term stability. Please note that this sensor will not work for temperatures below 0 degree.
This page covers the low cost DHT temperature & humidity or Grove – Temperature&Humidity Sensor . These sensors are very basic and slow, but are great for some basic data logging. The DHT sensors are made of two parts, a capacitive humidity sensor and a thermistor. There is also a very basic chip inside that does some analog to digital conversion and spits out a digital signal with the temperature and humidity. The digital signal is fairly easy to read using any microcontroller.
