PitSHT20 - Sensore di temperatura e umidità SHT20
L'utilizzo del sensore di temperatura e umidità SHT20 con interfaccia seriale i2c.
Cosa serve:
- Sensore SHT20
- cavetti
- libreria DFRobot_SHT20
Codice sorgente:
/*!
* @file DFRobot_SHT20_test.ino
* @brief DFRobot's SHT20 Humidity And Temperature Sensor Module
* @n This example demonstrates how to read the user registers to display resolution and other settings.
* Uses the SHT20 library to display the current humidity and temperature.
* Open serial monitor at 9600 baud to see readings.
* Errors 998 if not sensor is detected. Error 999 if CRC is bad.
* Hardware Connections:
* -VCC = 3.3V
* -GND = GND
* -SDA = A4 (use inline 330 ohm resistor if your board is 5V)
* -SCL = A5 (use inline 330 ohm resistor if your board is 5V)
