First and foremost, many thanks for your Hydrosys4. It is an awesome piece of software especially for gardening hobbyists who want to integrate IoT technology into their garden projects. Well done!
I am going to add only 2 sensors such as humidity, hygrometer to the system..however I am thinking to use capacitive analog moisture sensors instead with a ADS1015 12 bit Analog to DC. ( https://www.aliexpress.com/item/32886510546.html?spm=a2g0s.9042311.0.0.24624c4dzJ13vS )
Will Hydrosys4 be able to pick up the readings, sw library for this sensor included? Or is it restricted to the AP2192 and MCP3008 setup?
Thank you so much for the explanation! I am quite new to the electronic modules and sensors for the RPI. I do have some basic experience with GPIO, pull-up/down, DAC, resistance and all that. I will definitely give it a try and let you know. You have been very helpful and I appreciate your input on this.
Yes, I am aware of the varying resistance if I were to increase cable distance for the sensors. I read some people have tried low resistance CAT5 computer network cables, soldering them directly with much success but requires a bit of tweaking in the sensor values. they are cheap to obtain, has an appropriate gauge copper wire..so I will try that too. Will update you on this.
Many thanks again. Keep up the good work, your system is by far the best I've seen with thorough documentation and friendly support :)
