Wireless, battery-operated Mini air quality and weather station. Air quality, temperature, humidity, pressure, weather forecast. Designed on the RF52810, nRF52811, nRF52832, nRF52833, nRF52840 wireless radio modules. The temperature, humidity and pressure sensor BME280, temperature and pressure sensor BMP280, temperature and humidity sensor SHTC3, light sensor MAX44009, air quality sensor SGP40 is used The device is powered by CR2477 battery. Consumption when transmitting data is 8mA, in sleep mode is 325uA-35uA (see datasheet SGP40).
New arduino project. Wireless weather mini station with electronic ink display 2.9 inches (GDEH029A1 OR GDEM029T94), very low power consumption,compact size, housing with magnets. The device can use si7020 / 21, sht20 / 21, HTU20/21D or BME280 sensors. Use the MINEW MS50SFA RF module with nRF52832 chips, or the EBYTE E73 module with nRF52840 and nRF52833 chips.
It's a fully assembled and programmed compact wireless devices, atmospheric pressure, temperature, humidity, weather forecaster, illumination, charts with 2.9" e-paper display, resolution of 296 x 128 pixels. The device has an industrial look, at least I wanted to achieve this. The sensor has good energy efficiency. Powered by CC2530 chip (Zigbee).
