Sensirion launches the nSHT21, the world’s smallest digital humidity and temperature sensor. It consists of a newly designed sophisticated sensor chip encapsulated in a 3x3x1.1-mm DFN 3-0 package. Over-molding provides excellent protection against aging and ambient impact, such as condensation and harsh environments, guaranteeing long-term stability. The SHT21 is fully calibrated and provides an I2C digital interface. Analog output modes are available on request. The digital communication mode
enables superb low power consumption achieving a value in the range of 3μW. Typical sensor accuracy is ±2% RH over 20–80% RH and ±0.3 °C over 25–42 °C.
