Digital Temperature and Humidity Sensor for humidifier- HTU21D

Product Description

Digital Temperature and Humidity Sensor for humidifier- HTU*1D

Description

HTU*0D, is a new digital humidity sensor with temperature output of MEAS. Setting new standards in terms of size and intelligence, it is embedded in a reflow solderable Dual Flat No leads (DFN) package with a small 3 x 3 x 0.9 mm foot print. This sensor provides calibrated, linearized signals in digital, I²C format.

HTU*0D digital humidity sensors are dedicated humidity and temperature plug and play transducers for OEM applications where reliable and accurate measurements are needed. Direct interface with a micro-controller is made possible with the module for humidity and temperature digital outputs. These low power sensor are designed for high volume and cost sensitive applications with tight space constraints.

Every sensor is individually calibrated and tested. Lot identification is printed on the sensor and an electronic identification code is stored on the chip which can be read out by command. Low battery can be detected and a checksum improves communication reliability. The resolution of these digital humidity sensors can be changed by command (8/*2bit up to *2/*4bit for RH/T).

With MEAS improvements and miniaturization of this sensor, the performance-to-price ratio has been improved and eventually, any device should benefit from the cutting edge energy saving operation mode.

Optional PTFE filter/membrane (F) protects HTU*0D digital humidity sensors against dust and water immersion, as well as against contamination by particles. PTFE filter/membrane preserves a high response time. The white PTFE filter/membrane is directly stuck on the sensor housing.
