Description
Analog Devices, known for itsreliable and well-documentedchip sensors, has in its offer a precise and with high resolution digitaltemperature sensorADT7410. It's easy to usetemperature sensor for Arduino. Powered with the voltage from 2.7 V to 5.5 V. It communicates throughthe I2C buswith16-bit resolution(0,0078 ° C per lsb) or with default13 bits(0.0625 ° C per lsb).
|
The product is compatible with Arduino The manufacturer providessample codealong with the connection scheme for users ofArduino. |
ADT7410 has2 adress pins so on the same bus I2C, you can haveup to 4 sensors. It also has emergency pins with the break and the critical temperature. The sensor isvery accurate, and its temperature tolerancesare:
- ±0.5°C from -40°C to +105°C (2.7 V to 3.6 V)
- ±0.4°C from -40°C to +105°C (3.0 V)
Pins
The system has 8 pins in the form of holes for self-soldering, goldpin strips with the pitch of 2.54 mm (contained in kit).
| Pin | Description |
|---|---|
| VIN |
Supply voltage from 3.3 V to 5 V. |
|
GND |
The ground of the system. |
|
SCL |
Cloc line of the I2C bus. |
| SDA | The data line of the I2C bus. |
| A0 | The choice of the bus address. |
| A1 | The choice of the bus address. |
| INT | Output "Open-drain" pin of interrupt. |
| CT | "Open-drain" pin goes into a low state or a logical "0" when exceeding thecritical temperature threshold. (CT). |
Address I2C in ADT7410 is by default set on 0x48. If thisaddress is used by another sensor or if you want to connect severaltemperature sensorsADT7410on your device, you canchange the address I2Cfor a specific sensor using pins A0 and A1based on the following convention of the naming:
