5Pcs Soil Hygrometer Humidity Module Moisture Sensor
A part of the review has been auto-translated.
Did not tried it yet, but I received it in good condition and well packed
All right
These sensors work perfect during the first week. After that, the measuring points get all corroded, and measurement is IMPOSSIBLE !!! Too bad that I can't give 0 (zero) stars. How will we arrange the refund ?
Tested 2 of the 5 I purchased, work great! Very easy to set up on the Arduino - my indoor tomatoes love BangGood now!
sensore umidità perfetto, ottimo con l'uscita analogica e digitale impostabile direttamente con potenziometro a bordo scheda stampata
very good
Excellent
Interesting little trinkets - While they operate to spec for a short while, there is enough low current power flow to cause etching of the lead/solder on one leg of the probe... This could lead to dangerous circumstances should one try and use this product for human/animal consumption control environment... Lead oxide in water/soil is not a healthy thing!! Keep this unit as a short term "test if it works" type unit and should you wish to deploy it in a more permanent enviro, replace the probes with stainless steel wire/plate!
Arrived on time, well packaged - now its playtime - this will be very usefull for my hydrophonics project
Works as advertised but don't use that kind of things to monitor plants you plan to eat as it will relase metals in the ground as it corrodes, use capacitive probes (also sold on BG) instead for that.
