[Solved] TPM-200A-CO Carbon Monoxide sensor module datasheet?


Good morning (o;

Just received a CO Zigbee sensor in the hope it would work with ConBee II, but of course it doesn't (o;

Has anyone came across a datasheet for this TPM-200A-CO carbon monoxide sensor module?
All I see is the same HEX pattern coming out from a pin @ 9600 bits/sec, which is:

2C 00 00 03 E8 17

thanks in advance

Seems according to an Aliexpress product I've found it is quite simple...

--- Code: ---B1: 0x2C
B2: PPM-Highbyte
B3: PPM-Lowbyte
B4: 0x03
B5: 0xE8
B6: uint_8(B1 + B2 + B3 + B4 + B5)

--- End code ---

Which gives the simple checksum 0x17 for the sequence 0x2C 0x00 0x00 0x03 0xE8.

Wondering now how I could simulate carbon monoxide without burning down the house, as it always returns 0 ppm (o;
