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.

Code for Arduino IDE - https://drive.google.com/file/d/13wmxCt9XehJr1E2eyG1RnYsQTMb9A2LR/view?usp=sharing

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)

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.

Another one of my brand new device is ready, today I finished the case for this device. This is a motion sensor on the S16-L221D-2. Also added a temperature and humidity sensor, it can be sht20-21, si7020-21, hd 1080, perhaps something else, now there are many sensors in such cases. Powered by a "nuclear" battery 2/AA (14250) 3.6 V. Powered by a chip nRF52811. I added support for this chip to the sandeepmistry boards.

Soon this sensor will be available at openhardware.io

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

nice piece! Do you mean accelerometer for an encoder, or a physical one? And if the latter, what for is it supposed to be used?

I think the use cases quite a lot, I want to implement double tap. For example, there is a dimmable lamp with switching to cold and warm light. Here with the help of a double tap you can control the switch from cold to warm and back. In any case, I think this is a good extension of the functionality.

@neverdie Thanks for rating. Especially pleased, so as nRF52 for me began with Your those on this forum.
