Product Description:
Digital Temperature and Humidity Sensor HTU21D
DESCRIPTION
HTU21D, the new humidity and temperature sensor of MEAS is about to set new standards in terms of size and intelligence: Embedded in a reflow solderable Dual Flat No leads (DFN) package of 3 x 3mm foot print and 1mm height it provides calibrated, linearizedsignals in digital, I2C format.
HTU21D 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 humidity and temperature digital outputs. HTU21D sensors are low power consumption designed for high volume and cost sensitiveapplications with tight space constraints.
Every sensor is individually calibrated and tested. Lot identification is printed onthe sensor and an electronic identification code is stored on the chip – which can be read out by command.
Furthermore, the resolution of HTU21D sensor can be changed by command (8/12bit up to12/14bit for RH/T), low battery can be detected and a checksum improves communicationreliability.
With made improvements and the miniaturization of the sensor the performance-to-priceratio has been improved – and eventually, any device should benefit from the cutting edge energysaving operation mode.
