Product Name: Replace SHT2x digital output temperature and humidity sensor HT21D Series Model: HTU21S / HTU21P / HTU21D Brand: France Humirel Category: temperature and humidity digital output modules minimum volume digital output temperature and humidity sensors HTU21 Series Details: 1. Temperature Humidity Sensor HTU21 brief company based in France Humirel humidity sensing element is made of high-performance, temperature and humidity sensors for OEM applications HTU21 Series modules provide an accurate and reliable measurements of temperature and humidity. Diversified output, wide operating voltage range, but also has a high temperature and humidity precision accuracy. Temperature and humidity sensors HTU21 Series modules are designed for low-power small-volume application design, with good quality, fast response, anti-interference ability and cost advantages, small size, low power consumption, so that the temperature and humidity sensor HTU21 become the preferred variety of applications. 2. The temperature and humidity sensor Features: 1) miniature DFN package 2) one of the measuring temperature and humidity, the choice of a variety of output 3) free calibration 4) lead-free standards for reflow soldering 5) Low power consumption 6) Fast In response, a very small temperature effects 7) anti-condensation properties: 100% RH humidity in the lower 10s condensation environmental restoration measure 8) High precision: RH: +/- 2% RH-HTU21 T: +/- 0.3 ℃ -HTU21 HTU21D SHT11 SHT10 have relatively smaller size, only 3 * 3mm; at the same time can HTU21D Swiss SHT20, SHT21 full compatibility can be achieved on hardware Pin to Pin Pin, without modifying the circuit board. Software programs and also in Switzerland SHT20, SHT21 same can be achieved compatible replaced without making any changes. Meanwhile HTU21D than Switzerland SHT20, SHT21 has a very good price advantage, highly cost-effective digital output temperature and humidity sensor HTU21 application areas: digital output temperature and humidity sensor HTU21 applies: temperature and humidity transmitter, temperature and humidity recorder, temperature and humidity controllers, automotive electronics, home appliances, consumer electronics, printers, HVAC. nurture room, parenting room, HVAC, fresh air, room monitoring, agricultural greenhouses, weather and other fields.
