Wiring the 16-BIT ADT7410 High Accuracy Digital i2C Temperature Sensor

This is another sensor that works and runs on the i2C protocol produced and developed by Analog Devices Semiconductor, Analog Devices are known for their reliable and well-documented sensor chip and their primary electronics components. The Analog Devices ADT7410 is one of their top-notch temperature sensor featuring a high precision and high-resolution sensor with a 16-bit at 0.0078°C temperature resolution and 0.5°C temperature tolerance including an interrupt and critical-temperature alert pins with a supply voltage from 2.7v ~ 5.5v Logic, for each integration on your projects.

The ADT7410 has 2 address pins which means that you can have up to 4 sensors in one i2C communication BUS. For more technical details and configuration settings please refer to the technical datasheet below.

The ADT7410 Pin Configuration, Function and Descriptions

ADT7410 i2C Address – 0x49

PIN 1 | SCL | I2C Serial Clock Input. The serial clock is used to clock in and clock out data to and from any register of the ADT7410. Open-drain configuration. A pull-up resistor is required, typically 10 kΩ.
PIN 2 | SDA | I2C Serial Data Input/Output. Serial data to and from the part is provided on this pin. Open-drain configuration. A pull-up resistor is required, typically 10 kΩ.
PIN 3 | A0 | I2C Serial Bus Address Selection Pin. Logic input. Connect to GND or VDD to set an I2C address.
PIN 4 | A1 | I2C Serial Bus Address Selection Pin. Logic input. Connect to GND or VDD to set an I2C address.
PIN 5 | INT | Over-temperature and Under-temperature Indicator. Logic output. Power-up default setting is as an active low comparator interrupt. Open-drain configuration. A pull-up resistor is required, typically 10 kΩ.
PIN 6 | CT | Critical Over-temperature Indicator. Logic output. Power-up default polarity is active low. Open-drain configuration. A pull-up resistor is required, typically 10 kΩ.
PIN 7 | GND | Analog and Digital Ground.
PIN 8 | VDD | Positive Supply Voltage (2.7 V to 5.5 V). Decouple the supply with a 0.1 μF ceramic capacitor to ground.

CircuitPhython MCU Connections

First thing first you need to wire your AD7410 to your ESP32/RPI/PICO devices that support CircuitPython Firmware and hookup to: BOARD 3V –> ADT7410 – VCC / VIN | BOARD GND –> ADT7410 GND | BOARD SCL –> ADT7410 – SCL | BOARD SDA –> ADT7410 SDA

import adafruit_adt7410

# i2c = board.STEMMA_I2C()  # For using the built-in STEMMA QT connector on a microcontroller
adt = adafruit_adt7410.ADT7410(i2c, address=0x48)
adt.high_resolution = True

while True:
    print(adt.temperature)
    time.sleep(0.5)

  Controleer aansluiting van SCL / SDA :) Also Optrekken Resistors.
