It is a compact wireless micro weather station with a 1.54 Inch e-paper display with screen resolution of 200x200 pixels(GDEH0154D67), the highest resolution(number of pixels per 1 inch), the best contrast(black is black). The device has an industrial look, at least I wanted to achieve this, very, very thin. The sensor has very good energy efficiency. Powered by nRF52 multi-protocol chip (BLE, Zigbee, Thread, ESB). 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 MS50SFA supplied in several modifications with nRF52832 chips or RF module EBYTE E73-2G4M08S1C with nRF52840 chip.
Arduino development environment compatible.
The project uses e-paper display (GDEH0154D67) from Dalian Good Display Co.ltd.
Very long runtime with one or two CR2450 battery.
Consumption in data transmission mode - 8mA, in sleep mode 4.7μA.
The ability to install different sensors (si7020, si7021, sht20, sht21, htu20d, htu21d or bme280(sold with this sensor))
The case is printed on a FDM (PLA Carbon Black(оnly this option is on sale)). After printing, sanding and polishing is applied
Inside the case, magnet are installed for fixing to magnetic surfaces.
