Wireless expansion module for very cheap soil moisture sensor from Aliexpress

https://youtu.be/Toto1Cw4QBo

An updated version of my temperature and humidity sensor with e-ink. Now on nRF52840. Now it is not a module but a device in the case.

Replaced temperature sensor sht20 -- > > si7020
Added accelerometer.

In the near future the project will be posted updated on the website openhardware.io

My new mini multi device on nRF52810, nRF52811, nRF52832 chips. Designed specifically for a very small case from Aliexpress. It works!!!

bme280, sht20/21, si7020/si7021, hdc1080, max40009, lis2dw12, lis2dh12, lmt01, reed switch, led + rgb led, user button and 6 analog pins, 6 digital pins with NFC.

@magpern said in EFEKTA Temp&Hum sensor(ver. nRF52832 )+E-Ink display:

Seriously!!!!!!!!!!!!! It cannot be true!!! I have just ordered PCBs and all needed stuff to assemble it, and now the code is gone!!! Please post the code again, or make it available on alternative sites.. please. It is hundreds of dollars to waste otherwise!

The project will remain open, like others. I was in a bad mood that day:)... The rules of the site administration are reasonable, and the decision to open the project was mine.

My new project is finished today and put to the tests. This is a continuation of my other project - Wireless Module for Capacitive Soil Moisture Sensor v1.2.

Today I finished printing the case. Turned out to node with sensor bme280 and e-ink display, running on nRF52840 from SKYLAB

In one of the photos still have the sensor with bme280 working on nrf52840 from EBYTE. ...This is the previous project.

upd.

Another project of mine, the second revision is finished today and put to the test. This is an encoder with accelerometer, powered by nRF52811 chip (datasheet).

My new project of a temperature and humidity sensor with an electronic ink display 1.02 Inch ( GDEW0102T4 ), very low power consumption, very small device.

Hello,
sorry for my poor english.. I don't speak it very well...
I just want to know if you plan to sell assembled card in the future? I'm very intersted by your project but don't have the possibility to sold the component.
Thanks for your answer.... and I cheer all of your project.

Yes, I am planning to sell this device in assembled form. Even now, there are many orders that I am very slow to complete. The problem with both COVID-19 and the fact that I am not very happy with the Chinese sensors that are used in my project. I will replace them with my own and soon complete all orders.

prototype e-ink1.54 V4, even smaller, even faster
GDEH0154D67 + nRF52832 First SW test. – 01:25

@NeverDie From these things, which are in the photo above, can make an informant COVID-19. Show the trend, the number of infected people to date in your location, and so on.

The other day I received PCB of a long-awaited project. Yesterday and today, I soldered the device, designed and printed the case of the device. It works, wow!!!

@ncollins And this is my simple capacitive button, just a button:). Beginning of this story was like this:... once I bought a Chinese capacitive button and was very upset with the quality...
