product name:Temperature and humidity digital output HTU20D
Product number:HTU20D
category:Temperature and humidity digital output module
Product Description:
New generationHTU20DTemperature and humidity sensors have established new standards in
terms of size and intelligence: it incorporates double row flat
pinless for reflow solderingDFN Encapsulation, Bottom3xprefix = st1 3mm ,height1.1mmThe The sensor outputs the calibrated digital signal, standard I2C format. Diversified output mode, wide operating voltage range,
while high temperature accuracy and humidity accuracy.HTU21Series of modules designed for low-power small-volume application
design, with good quality, fast response speed, anti-interference
ability, cost-effective advantages, small size (3x3mm), Very low power consumption
Sensor important parameters:

SHT21 SHT20 has a smaller volume relative to SHT11
SHT10.SimultaneouslyHTU21DCan be with the SwissSHT20,SHT21Implementation is fully compatible, the hardware pin can be
achievedPin to Pin, No need to modify the circuit board. The software program also
works with SwitzerlandSHT20,SHT21The same, can be compatible with the replacement, without making
any changes. SimultaneouslyHTU21DCompared to SwitzerlandSHT20,SHT21Has a very good price advantage, very cost-effective
