Zest_Sensor_P-T-RH

Overview

The Zest_Sensor_P-T-RH is an electronics development board for 6TRON open source platform featuring 3 environment sensors (humidity, temperature, pressure).

The Zest_Sensor_P-T-RH integrates the following elements:

  • A humidity sensor HTU21DF from TE Connectivity. It is specially dedicated for humidity and temperature. It is configured to measure air humidity between 0 ~ 100 %HR

  • A temperature sensor AS6212-AWLT-S from AMS. It provides a 16-bit resolution over the full temperature range from -40°C to +125°C and integrated alarm functionality enables micro-controller wake-up calls at defined temperature thresholds

  • A pressure sensor 2SMPB-02E from Omron Electronics. It is configured to measure the pressure of air between 30kPa and 110kPa and integrates a temperature compensation circuit to ensure accurate absolute pressure measurements.

The Zest_Sensor_P-T-RH offers 6TRON users a P-T-RH sensors able to measure 3 environment parameters (humidity, temperature, pressure) to monitor air quality in health, environmental and industrial applications.
