IR Sense 6 Click

How does it work?

IR Sense 6 Click is based on the ZTPD-2210, a thermopile sensor from Amphenol, designed for precise non-contact temperature detection. This sensor provides a fully calibrated digital output and covers a measurement range from -20°C to 100°C, making it suitable for a wide variety of temperature monitoring applications. Thanks to its built-in ambient temperature compensation, the sensor ensures accurate readings even in fluctuating environmental conditions. Additionally, it features a configurable Sleep mode via register settings, allowing for reduced power consumption in energy-sensitive designs. The optical field of view spans approximately 90 degrees at 50% of maximum output, enabling broad area coverage. IR Sense 6 Click is an ideal choice for applications such as non-contact thermometers, automotive cabin temperature control, building HVAC systems, and smart home appliances including microwave ovens and refrigerators. It also finds valuable use in healthcare settings, particularly for monitoring human body temperature without physical contact.

IR Sense 6 Click is designed in a unique format supporting the newly introduced MIKROE feature called “Click Snap.” Unlike the standardized version of Click boards, this feature allows the main sensor area to become movable by breaking the PCB, opening up many new possibilities for implementation. Thanks to the Snap feature, the ZTPD-2210 can operate autonomously by accessing their signals directly on the pins marked 1-8. Additionally, the Snap part includes a specified and fixed screw hole position, enabling users to secure the Snap board in their desired location.

This Click board™ uses an I2C interface with clock speeds of up to 3.4MHz, ensuring fast communication with the host MCU. In addition to the I2C interface pins, IR Sense 6 Click features an EN pin used to control the MAX40200 ideal diode, which in this design acts as a power switch. When the EN pin is activated, it enables the MAX40200 to supply power to sensor on the board. This setup allows power management by enabling or disabling the sensor as needed, making it especially useful for low-power and battery-operated applications.

This Click board™ can operate with either 3.3V or 5V logic voltage levels selected via the VCC SEL jumper. This way, both 3.3V and 5V capable MCUs can use the communication lines properly. Also, this Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used as a reference for further development.

Click Snap

Click Snap is an innovative feature of our standardized Click add-on boards, designed to bring greater flexibility and optimize your prototypes. By simply snapping the PCB along predefined lines, you can easily detach the main sensor/IC/module area, reducing the overall size, weight, and power consumption – ideal for the final phase of prototyping.
