Perfect for targeted measurements

The narrow field of view is exactly what I needed for my project. Unlike the standard 90-degree sensors, this one allows me to measure specific components without interference from surrounding heat sources. Highly recommended for precision work.

Best long-range option

Much better than the standard version for distance measurements. I can measure the temperature of objects further away with much better accuracy due to the narrow FOV. Great addition to my toolkit.

Accurate and stable

Using this for machinery monitoring in a small enclosure. The readings are stable and consistent over long periods. The long-range capability helps keep the sensor away from direct heat exposure.

Good sensor, tricky setup

The hardware itself seems solid, but I found the initial setup a bit confusing. Documentation could be more detailed for beginners. Once working, it performs as expected.

Works well with Arduino

Easy to integrate into my Arduino setup. The library support is decent. Just make sure to check your voltage levels before connecting to avoid any issues. Good value for the price.

5 FAQ

Q: What is the exact field of view angle?

A: The DCI version features a 5-degree field of view, which is significantly narrower than the standard 90-degree versions.

Q: Is this module 5V tolerant?

A: Yes, the module includes a voltage regulator and is safe to use with 5V logic systems like standard Arduino boards.

Q: Is calibration needed out of the box?

A: The sensor is factory calibrated. However, advanced users can adjust calibration settings via the I2C interface if specific application needs require it.

Q: Does it work with Raspberry Pi?

A: Yes, it is compatible with Raspberry Pi via the I2C GPIO pins. Ensure you enable I2C in the raspi-config settings.

Q: What is the maximum measurement distance?

A: Distance depends on the target size. For accurate readings, the target should completely fill the field of view. Generally, it works well for distances up to several times the target diameter.
