Description

Module with digital temperature sensorMCP9808 equipped with a communications I2C interface (TWI). Pins are the popular goldpin connectors, to connect the sensor to the main module (e.g. Raspberry PiorArduino) viawires.

 

The product is compatible with Arduino

The manufacturer providessample codealong with the connection scheme for users ofArduino.

 

 

Pins

 

Pin Description
VDD Supply voltage in the range from 2.7 V to 5.5 V.
GND The ground of the system.
SCL Clock line of the I2C bus (installed resistor pulling-up 10 kΩ).
SDA The data line of the I2C bus (installed resistorpulling-up 10 kΩ).
ALERT The external interrupt of open collector type.
A0, A1, A2

Pins of address selection of I2C bus. Default adress is: 0x18. Indicating the high status on a single bit will lead to the change of address in accordance with patterns: 0x18 + A2 + A1 + A0.

For example, when indicating a high statusn on all bits, the address will be: 0x18 + 4 + 2 + 1.

When we indicate a high status only on A2 and A0, then: 0x18 + 4 + 1 = 0x1D.

Accurate temperature sensor. Powered by 3.3v on the EPS32 platform together with the BMP280. Thanks to the possibility of addressing, several of the same modules can be connected and used in the weather station. 1 in a cage and the other next to the ground, 3 in full sun.
