Wireless, battery-operated Mini air quality and weather station. Air quality, temperature, humidity, pressure, weather forecast. Designed on the nRF52810, nRF52832, 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). The device has an industrial look, at least I wanted to achieve this. The sensor has very good energy efficiency. Powered by nRF52 multi-protocol chip (BLE, Zigbee, Thread, ESB), nRF52833 and nRF52840 versions. The device comes preinstalled with MySensor Protocol (ESB) wireless networking software - www.mysensors.org, can also work as a standalone device without a network. Can use both a ready-made device and a device for developing your own software right away.
I am interested in making original devices that are not on sale.
Right now, I'm very interested in low-power, cost-effective wireless devices.
RF module MINEW, EBYTE with nRF52810, nRF52832, nRF52833 or nRF52840 chip.
Arduino development environment compatible.
The project uses e-ink display (GDEH0213B72) from Dalian Good Display Co.ltd or 2.13inch e-Paper V2 from Waveshare Electronics.
Very long runtime with one or two CR277 battery.
Consumption in data transmission mode - 8mA, in sleep mode 35uA (see datasheet SGP40).
Reverse polarity protection
Sensors on the board: sgp40, bme280 OR bmp280+htu21d, max44009(optional)
The case is printed on a FDM 3D printer, color: PLA Black. After printing, the case is further sanded and polished.
Pre-installed software has multilingual support.
Inside the case, magnet are installed for fixing to magnetic surfaces.
!!!Now there is an increase in prices for electronic components, for example, the bme280 sensor rose in price by more than 100% in March 2021.!!!
