It is a compact wireless multisensor (temperature, humidity, pressure, forecast, light) with a 2.13Inch e-ink display, resolution of 250 x 122 pixels. 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.
You can see how it works in my small video.
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 with 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 CR2450 battery.
Operation with CR2430, CR2450, CR2477 batteries (300mA - 1900mA), on sale version with CR2450 holder.
Consumption in data transmission mode - 8mA, in sleep mode 4.7μA.
Reverse polarity protection
The ability to install different sensors (bme280, si7020, si7021, sht20, sht21, htu20d, htu21d, max44009), on sale version with bme280+max44009(optional).
The case is printed on a FDM 3D printer, color: PLA Carbon Black, PLA Marble. 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.!!!
