Capacitive Soil Moisture Sensor
Log from Sensors Based on the Padauk RFC Peripheral
One curious type of sensor that can be realized with simple means is a soil moisture sensor to monitor wether plants need to be watered. A simple way of achieving this is to measure the soil resistivity with two electrodes. Unfortunately that is not...

Soil Moisture Sensor Unit Testing
Log from AGI-ESP8266
I have setup an Arduino Uno connected to both moisture sensors. The objective of this test is to determine how well each unit functions in it's intended environment.As you can tell from the above image, I've taken a couple of lettuce seedlings and placed...

Testing the Soil Moisture Sensor
Log from lowcost full automated watering robot
To test if the soil moisture sensor is working correctly, I hooked up a simple digital tube display. The sensor is connected to an analog pin. So if there is high moisture, the read value is high (a few hundred). If it were totally dry it would show...

Log from ESP8266 EasyIoT Arduino library
Added new water leak (soil moisture, rain) sensor example.ESP8266 WiFi water leak (soil moisture, rain) sensor example

Hacking a Capacitive Soil Moisture Sensor for Frequency Output
Log from The Cave Pearl Project
Ok, right up front I'll admit that combining an $1 ADS1115 board with these cheap soil moisture probes is already a decent soil moisture solution for most projects. So I was just messing around here to see what I'd get: https://thecavepearlproject.org/2020/10/27/hacking-a-capacitive-soil-moisture-sensor-for-frequency-output/Pin...

Soil Percolation Test
Log from Vinduino, a wine grower's water saving project
Last weekend before the Hackaday Prize entry closes. And what a weekend it was!!With these extreme temperatures, reaching 110F (43C), each grape vine consumes 4 gallons per day. Irrigation is set to replenish the daily use of the vines in the coming...

Capacitive soil moisture
Log from Keep the basil alive
Ok i wanted to use the Chirp as a soil moisture sensor but they are out of stock :(Than I started thinking, why spend extra money on a seperate sensor? The teensy LC has some very capable capacitive measuring pins on its own.So from some left over PCB...

On soil moisture sensors...
Log from Magnificent Moisture Management
Too dry and your plants will wilt. Too wet, and the roots will rot. So you're going to need a moisture sensor.The standard method in the hobbyist community seems to be a resistive sensor. You take two electrodes, e.g. two nails, put them in the dirt...

Soil and CO2
Log from Growing vegetables in sealed containers
I want to test a hypothesis that if I start with initially dry soil, then add a small quantity of water (and some microbes on a small piece of damp soil), I will end up with an escalating production of CO2: the small quantity of water will allow some...

soil moisture probe
Log from Rezodo: Long Range irrigation and weather station
Soil moistures probes are based on 3 classical technologies: resistive probescapacitive probestensiometer probes Each technologiy has advantages and drawbacks. resistive probes wear down when using as their electrodes will destroy with electrolysis when...

soil reading take 2
Log from rain water irragation controler
tonight I am fixing the soil moisture inputs putting voltage dividers on the out put f the soil moisture sensors to protect the analog pins on the photon and tomorrow it will be re installed in a new encousure

Soil/Heater Test Update
Log from OPEN - Open Propagator with an Extensible Network
Just finished testing the soil heater, after three hours given the temperature constraint on the heater of 40C the overall soil temp is around 30C. A relative rise of 5 to 7 degrees C given room temperature has been between 23C and 25C. To conclude,...

My First Prototype (outside of soil)
Log from The Compost Professor - A Smart Composting System
June 2 2017 -I've assembled the sensors and actuators into a bird's nest of wires... but, it works fine for a prototype. The attached video shows how the assembled prototype will work (I wanted to show the components before I added them into the composting...

Soil Moisture Calibration
Log from Low Power High Accuracy Weather Station
Having tried both capacitive and resistive moisture sensors, I found the resistive much more stable and accurate and then spent a bit of time calibrating it against changes in temperature: The blue line shows how the moisture readings change with temperature...

Soil Probe Update
Log from Plant Friends
About the soil probes on ebay, I don't know if they use the lead-free tin type or the leaded type for the finishing hence in my article I mentioned they 'might' contain lead. And frankly, I don't really trust the eBay sellers to provide me with correct...
