WüRTH ELEKTRONIK WSEN-HIDS series digital humidity MEMS (Micro-Electro-Mechanical System) sensor measures with a precision of ±1.8% RH in the 20 – 80 percent relative humidity range. The DFN (Dual Flat No Leads) package for SMT assembly measures 1.5 x 1.5 x 0.5 mm. Sensor works with a current of only 0.4µA and can be operated with a power supply between 1.08 and 3.6V. It is suitable for distributed IoT sensor networks, such as those in smart farming applications.
