Thermo 4 Click-Platine

The Thermo Click Board™ carries the NXP LM75A digital temperature sensor and thermal watchdog. The sensor has the  range from −55 °C to +125 °C . The click is designed to run on either 3.3V or 5V power supply. It communicates with the target microcontroller over I2C interface, with additional functionality provided by the INT pin on the mikroBUS™ line.

LM75A Features

The NXP LM75A is a temperature-to-digital converter using an on-chip band gap temperature sensor and Sigma-delta A-to-D conversion technique. The device is also a thermal detector providing an overtemperature detection output.

The sensor can be configured for different operation conditions. It can be set in normal mode to periodically monitor the ambient temperature, or in shutdown mode to minimize power consumption.

The temperature register always stores an 11-bit 2's complement data giving a temperature resolution of 0.125 °C. This high temperature resolution is particularly useful in applications of measuring precisely the thermal drift or runaway.
