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,...

Soil humidity indicators
Log from Pal plant
The screen shows the humidity of the water through three different icons: This one indicates that the soil is low on water and you should water your plant. -- This one indicates that the soil humidity is just right. -- This one shows...

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...

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...

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...

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 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 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...

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 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...

Agar instead of soil?
Log from Biotop
For the first experiment, 4g of agar was boiled in 100 ml of distilled water, and 2 ml of universal liquid fertilizer was stirred in. After cooling, some dill seeds were placed on the agar surface and watered. I then used a toothpick to make holes in...

Measuring Soil Resistivity with Multimeter +
Log from Multimeter +
I was working with my son on his science project “Impressed Current Cathodic Protection in Presence of AC Interference.” Impressed current cathodic protection is used to protect pipes (oil, gas, water lines) from rapid corrosion. Rectifiers...

ESP soil moisture sensor V2.1
Log from ESP Soil Moisture Sensor
New sensor with full GPIO. Replace DHT11 with tmp112
