HiGrow is a Soil Moisture, Temperature, Humidity sensor. HiGrow communicates with a cloud application for uploading data and the user can check his plants and sensor with an app.It uses ESP32 to powered by lipo battery, a Soil Moisture sensor and a DHT11 Temp and Humidity sensor.
HiGrow hardware is almost opensource. We'll publish very soon the instruction to assemble your HiGrow and 3D print the case on http://www.higrow.tech
You can find the ongoing firmware udpates, based on Arduino IDE, on GitHub: https://github.com/lucafabbri/higrowopen

To the ones interested in developing apps working with ESP32 we are also doing a porting of ESP TOUCH Smart Config to Xamarin. So you can integrate the libraries in your cross platform pr

Hi people, I have a problem with your sketch!
Error during compilation. Can tell me what to do?

I took it from here: https://github.com/lucafabbri/higrowopen

Maybe it's in the DHT sensor library.
which library do you use?
The error is this:

There may be a problem in the DHT library?

Be so kind as to tell me!

Hi, im looking into this project and bought two sets of PCB from aliexpress (this is where I stumbled onto it). Before loading any code to it I discover that my two boards does not have the transistor/FET, the 3 pin SMD component in the bottom part (toward soiltail). Does it exist any electrical drawing to this board so that I can investigate the board and its components?

is there a voltage divider to monitor the battery?

on which pin is it?

are there any more infos about the board?

which sensor is on which pin?

why is the github sketch not maintained?

Hi Luca,  I'd be very interested in purchasing one of your ESP32 dev boards for my project, are they available on any other online stores other than Amazon.it

  Are you sure? yes | no

you will get the PCB with the ESp32 onboard. Batterie 18650 and housing are not included. How’re this helps.
