Fonctionne bien, très configurable, plusieurs options de capteur

J'aime vraiment cet appareil car il permet plusieurs options de capteur dans diverses configurations. Capteurs de température multiples, capteur d'humidité, poids, PIR, ADC, etc. Vous devez cependant travailler dans les différents modes de travail. J'ai fait des tests à portée limitée avec la petite antenne fournie. 2,3 milles à -105rssi ; 8 snr. Depuis, j'ai commandé quelques autres de ces unités. Le prix est imbattable !

Works well, very configurable, multiple sensor options

I really like this unit as it allows for multiple sensor options in various configurations. Multiple temp sensors, humidity sensor, weight, PIR, ADC, etc. You do have to work within the various working modes though. I've done some limited range testing with the small antenna it comes with. 2.3miles at -105rssi; 8 snr. I've since ordered a couple more of these units. Can't beat the price!
