Donate to support Open HardwareWireless, battery-operated Mini air quality and weather station. Air quality, temperature, humidity, pressure, weather forecast. Designed on the nRF52833, nRF52840 wireless radio modules. The temperature, humidity and pressure sensor BME280, air quality sensor SGP40 is used The device is powered by CR2477 battery. Power consumption when transmitting data is 8mA, in sleep mode is 35uA (see datasheet SGP40).
Please see the current version of the software on my github, it is updated quite often
Works with MySensors.
Not a bad device to start learning nRF52 and e-paper
