The HTS221 humidity sensor is the first environment sensor from STMicroelectronics which follows the train of new open cavity combos. Assembled in a 6-pins LGA 2 x 2 x 0.9mm package; the HTS221 is a digital humidity and temperature sensor equipped with a sensor die and an ASIC. It has operating ranges of -40…+125°C, 0…100 % relative humidity for 16bit output data for temperature and humidity.

The relative humidity sensor uses a polymer dielectric planar capacitor digital measurement technology which allows a precise response in very compact size. The integrated heater allows a high ODR.

This device uses a new type of package built around an original holed cap developed by STMicroelectronics for mobile phones and for industrial application with a temperature range from -40 °C to +120 °C.

The report presents deep technology and cost analysis of HTS221 with an exhaustive package analysis. It also includes a technology and production cost comparison with Bosch BME280 humidity and pressure sensor and with Sensirion SHTC1 humidity MEMS.
