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.
Temperature humidity sensors comparison (Data) Part 3
Wherever I go, peoples asked me why I chose DHT12, and why I spent time to write a library for this small sensor, in this articles I’ll try to give an answer (competitor bmp280, DHT11, DHT22, Dallas and thermistor).
Finally the comparison.
Temperature humidity sensors comparison (Code configuration) Part 2
Wherever I go, peoples asked me why I chose DHT12, and why I spent time to write a library for this small sensor, in this articles I’ll try to give an answer (competitor bmp280, DHT11, DHT22, Dallas and thermistor).
Today the code to get sensors fully working.
Temperature humidity sensors comparison (Specifications) Part 1
Wherever I go, peoples asked me why I chose DHT12, and why I spent time to write a library for this small sensor, in this articles I’ll try to give an answer, and introduce the competitor bmp280, DHT11, DHT22, Dallas and thermistor.
Today the specification of the sensors I use.
DHT12 i2c Cheap Humidity and Temperature Sensor
This is an Arduino and esp8266 library for the DHT12 sensor, a very low cost temperature/humidity sensors (less than 1$) that work with i2c or one wire connection
