The Silicon Labs Si7006-A20 is an I2C interface, ultra-small, Temperature and Humidity Combination IC. It is offered in a 3x3x0.75mm DFN-6 package. The Si7006-A20 provides 0-90% RH with an Accuracy of +5% (max). It is operational from 0-100% RH. The Humidity sensor is configurable from 8-12bits with conversion times from 2.6-10ms respectively. The SI7006-A20 incorporates a ‘heater’ element to aid in testing the sensor, to dry the sensor membrane, or to implement a dew-point. The Si7006-A20 measures Temperature with a typical accuracy of +0.5 °C accuracy and can measure Temperature across the full industrial temperature range(-40°C to 125°C). The temp sensor is configurable from 11-14bits with conversion times of 1.5-7ms, respectively. The Si7006-A20 operates from 1.9 to 3.6V supply and has a Typical Sleep Mode current of 60nA with an IDD during Humidity Measurement of 150µA and 90µA during Temperature Measurement. The smSENSR-Si7006 provides an easy to use, low-cost, very small breakout board for the Si7006-A20. All pins are all mapped to standard 2.54mm/0.1” headers. This allows for use in a standard bread-board or to be ‘wired’ into an application. The header-header spacing is 7.62mm (300mil). It comes with I2C pull-ups on-board.

All SMSTRS smMEM, smSENSR, smCOM, smBAT, smPWR products are compatible with the Sensor Maestros Wireless Sensor Platforms that provide Rapid prototyping for Sensor and BTLE applications. The smSENSR-Si7006 can be plugged into ANY of the 8pin smBLOCK I2C sockets in the smWSP and smWSP-ARD rapid prototyping sensor plugin boards.
