Hacking A Thermal Imager For Twin-use Of The Thermal Sensor

Typically a tool doesn’t do fairly what one wants, and in these instances a little bit of tampering would possibly do the trick. That’s what led to having the ability to document video from a HTI HT-A1 thermal imager regardless of the machine not truly supporting that perform, because of cautious investigation and guarantee violation.

Plugging in a {custom} USB cable permits a cell phone app to entry the thermal sensor, whereas the host machine itself stays ignorant.

We’ve seen a teardown of the HT-A1 up to now, and it seems that Search — the producer for the precise thermal sensor contained in the machine — launched an OEM improvement equipment and cell phone app for his or her modules. May this imply that the uncooked sensor module within the HT-A1 could possibly be accessed by way of the developer equipment app? One hacked collectively USB cable later confirmed that the reply is sure! Not solely does the app enable viewing thermal imagery, but it surely makes it attainable to do issues like document video (a perform the HT-A1 itself doesn’t assist.)

However even when the HT-A1 doesn’t enable recording, as a handheld thermal sensor with a display screen it’s nonetheless fairly helpful in its personal means and it could be disgrace to intestine the unit only for a uncooked sensor module. The most effective answer ended up being to place the sensor again into the HT-A1, and set up some switching circuitry to disconnect the sensor from the HT-A1’s CPU and divert its knowledge to the USB plug on demand. This implies the HT-A1 can be utilized usually, however by plugging in a custom-made cable whereas the unit is off, the thermal sensor may be accessed by the cell phone app as a substitute. Better of each worlds. You may see a short celebratory thermal cat video embedded beneath, proving it really works.
