The housing does not fit together easily. In order to save slightly longer screws, the bottom plate is too close to the PCB, so that the protruding wires of the parts ensure that the bottom plate is bent. An annoying fact is that it has not been thought that you have to screw the module. If the bottom plate had been made two centimeters wider and had two extra holes, this problem was solved. Of course we were curious how the accuracy of such an extremely cheap device looks like. We compared the reading of the NTC sensor with that of a type-K thermocouple coupled with a precise Lascar thermometer. The average error is ± 1.43 ° C and that is good enough for a thermostat. At around room temperature (+20 ° C) the error was the smallest but the deviation increases, both to lower and higher temperatures. At a reference temperature of -5 ° C the W1209 indicated a temperature of -7.2 ° C. At a reference temperature of +100 ° C the module claimed that it was +102 ° C.
