Easy to set up and use.

Works great! We use it to monitor our mushroom room.

Ca semble etre un très bon produit, sonde précise, construction fiable... mais il est vraiment pas simple a programmer, instruction juste en anglais et affichage pas trop trop clair ! je travaille en instrument / contrôles depuis plus de 30 ans ! bonne chances !

Seems well built, should last. I can't verify how accurate it is, but it does seem to respond quickly if I blow in the direction of the sensor. I am using it to keep CO2 low in a room with a reef aquarium. I hooked up a power supply from this sensor to a Konnected Wifi module that integrates into Samsung Smartthings to control some exhaust fans and a powered valve on a CO2 scrubber. Works well. Before hooking this up, CO2 levels were hitting as high as 1,300. Now its down to about 490. Not super intuitive to set up, but not too hard. Take your time and read the instructions, maybe a few times. All in all, very happy with the product.

This will not work with their other systems and will conflict with the automation of your tent. The sensor is good but that's it. This is a poor design and should be changed.
