SHT21 SHT20 itself for the chip package, welding difficult. Welding temperature is not good, easy to damage the chip. Buy 2.54 standard spacing, pin type SHT20 or SHT21 is the best choice for the first time contacts.
SHT20SHT21.
Main features:
SHT20Digital temperature and humidity sensors areSensirionThe company's new temperature and humidity sensors, based on the world's leadingCMOSensDigital sensor technology, this product in terms of dimensions and the establishment of a new set of standards, both the use of advanced bilateral or square flat lead-free package.DFN),3*3Mm, linear digital output,2Wire system interface. In the high humidity testing environment, the performance is stable, beyond the excellent performance of theSHT1xandSHT7x
erery SHT20Digital temperature and humidity sensors have been calibrated and tested separately.LOTIdentification code, in addition to the electronic identification code can be read stored in the chip, low power input detection and calibration can help improve communication stability.
Application domain:
Data acquisition, transmitter, automatic process control, site, agricultural greenhouses, flowers, nursery, lawn and other environmental measurement needs to be detected in soil temperature and humidity. Metal packaging, more suitable for a large part of the dust, the environment is more severe occasions to use
