This demonstrates reading object temperatures with an All-Sun (http://www.e-sun.cn/) EM520B infrared thermometer. This has been tested with one rebranded as CEN-TECH #96451 (8:1 distance to spot, plus laser), from Harbor Freight. There are several models similar to the EM520B, with slightly different specs which may also work, though it's completely untested as I don't have access to any of them.
- INIT: Unsure, some initialization pin, likely for factory testing (screen momentarily displays Conn when grounded)
- RX: Receive
- GND: Ground
- TX: Transmit
