EnvSens is a compact sensor module for ambient air and brightness monitoring with an ESP-12E Wifi microcontroller. It runs until a minimal battery voltage from 2.5 V properly. Ideal for IoT applications!
With help of the BME680 sensor from Bosch, temperature, humidity, air pressure and air quality can be measured in a very energy-saving way. In addition, LITE-ON's LTR303 digital ambient light sensor enables the monitoring of daylight and lamp light close to the spectral viewing range. A real-time clock (RTC) AB0805 from Abracon provides the time for the measuring points with low power consumption. All modules are connected to ESP-12E via I2C bus.
