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).

@nca78 said in What did you build today (Pictures) ?:

What resin do you use ? Can you share (by MP if you want) a screen capture in slicer to see how you print it (support etc).
Just bought a SLA printer and still learning, that would help me as I have similar enclosures to print.

Anycubic Resin. All my projects are always fully available on my github (Gerber, hull models, schematics, codes)

@NeverDie My experience shows that the Chinese sensors that are sold on Aliexpress have a low quality printed circuit Board. When used outdoors, they may deteriorate within 1-2 seasons. Inside the house, in a flower pot, the service life is much longer. As for such sensors developed independently, the quality of printed circuit boards that are ordered through the services of jlcpcb, pcbway... very high.

Will software be available for testing?

Hi, everybody. A new version of the device(V3) is currently being tested. Now this device is in its own case. Works on MCU nRF52810, nRF52811, (in sleep mode 2μA) NRF 52832 (sleep 3.7μA) and nRF52840 (sleep 4.7μA). Power from 2x2450 or 2x2477. There will be an update soon on openhardware.io.

Amazing project! I want to repeat it, but there is a problem. I can't find the T1 transformer where you bought it.

I don't remember exactly, but I think in my case it was due to using wait b sleep in before() and presentation(). This may be due to the power of the radio module.

Recently, I have faced exactly the same situation. Since this is no longer an isolated case, it means that the case is in the mysensors library.
