GY-273 QMC5883L clone HMC5883L magnetometer for Arduino, esp8266 and esp32
The sensor GY-273 QMC5883L clone HMC5883L magnetometer for Arduino, esp8266, and esp32 is cheap and reasonably precise but needs some check for the clone version.

GY-291 ADXL345 i2c spi accelerometer with interrupt for esp32, esp8266, stm32 and Arduino
The ADXL345 is a small, thin, ultralow power, 3-axis accelerometer with high resolution (13-bit) measurement at up to ±16 g. This device works with i2c and SPI protocol and Is suitable with Arduino, esp8266, stm32, and esp32.
LoRa remote water level and pump controller (ReWaL): assemble client and 3D printed case – 7
I must fill a tank 1.5 km away, so I create a 2-part controller.
A server with a relay to manage the pump and a client solar/battery-powered to check the tank’s status and notify to the server.
Now we put all the Client components in the relative Case.

I must fill a tank 1.5 km away, so I create a 2-part controller.
A server with a relay to manage the pump and a client solar/battery-powered to check the tank’s status and notify to the server.
Now we put all the Server components in the relative Case.
LoRa remote water level and pump controller (ReWaL): Client PCB – 5
I must fill a tank 1.5 km away, so I create a 2-part controller.
A server with a relay to manage the pump and a client solar / battery-powered to check the tank’s status and notify It to the server.
Here we are going to assemble the Client PCB.
LoRa remote water level and pump controller (esp8266): Server PCB – 4
I must fill a tank 1.5 km away, so I create a 2-part controller.
A server with a relay to manage the pump and a client solar/battery-powered to check the tank’s status and notify the status to the server.
We are going to assemble the Server PCB.
LoRa remote water level and pump controller (ReWaL): client software – 3
I must fill a tank 1.5 km away, so I create a 2-part controller.
A server with a relay to manage the pump and a client solar/battery-powered to check the tank’s status and notify the status to the server.
Here we are going to look at the Client software.
LoRa remote water level and pump controller (esp8266): server software – 2

Ebyte LoRa E220 device for Arduino, esp32 or esp8266: manage Wake On Radio and sends structured data – 5
In this article, we look at the Wake On Radio (WOR), one of the essential features of our Ebyte E220 UART LoRa device based on LLCC68 Wireless Modules.
Then we understand how to manage complex structures that are better optimized than string format data.
LoRa remote water tank level and pump controller (ReWaL): intro – 1
I have to fill a tank 1.5 km away, so I create a 2-part controller.
A server with a relay to manage the pump and a client solar/battery-powered to check the tank’s status and notify the server’s status.
Here is a little introduction to the project with the list of devices and libraries.
