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...

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...

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...

Components ordered.
Log from AGI-ESP8266
I have ordered the following soil moisture sensors for testing:-Gravity Soil Moisture sensor This sensor's surface is gold plated using an immersion electrolysis process. Compared to conventional soil moisture sensors, it should last longer. I'm expecting...

New ideas
Log from Keep the basil alive
Ok, so my quick and dirty capacitive sensor is not very successful. Maybe it is that it needs temperature compensation, maybe I am just measuring noise. The biggest problem is that I do not know.So time to collect data. I have bought a ESP8266 board...

i have an idea!
Log from A cheap capacitive soil moisture sensor
It has passed some time since i upload a log for this project, a lot has happened in my personal life and in this project too.First, i finished the prototype of the sensor and i made two of them to compare their performance. I used some servo cables...

Starting with the sensors!
Log from homefarm
So I finally got started with some sensors! Here are the sensors I started with: One Wire Temperature Sensor (Grove) [DIGITAL] Wiki: https://wiki.seeedstudio.com/One-Wire-Temperature-Sensor-DS18B20/Capacitive Soil Moisture Sensor (Grove) [ANALOG]...

Designing and building add-ons
Log from MI/O
1. USB power supply and a reading light USB power supply add-on gerber rendering: I added two additional solder pads (power isolation jumper) to enable the power indicator LED. Some may need it, some not. Reading light add-on gerber rendering: The LED...

Hardware design
Log from ESP32 Soil Moisture Sensor with Flip-Dot
Recently we bought some new plants to fill up some of the space after we moved to a larger house. I am not the best plant owner, and need to be reminded when to water these new housemates. Roughly at the same time, I found a cool new component, that...

Sensors to consider!
Log from conscientious koala
To note with these gas sensors: we'd want a fan to get good ambient air flow into the enclosure containing the sensors! PM 2.5 Nova PM Sensor SDS011 (0.3 to 10μm) https://components101.com/sensors/nova-pm-sensor-sds011-pinout-features-working-applications-datasheet ...

IoT with Espoir Part 2: Applied gardening
Log from Espoir
New guide: smart, open source, IoT irrigation system Last week, I covered how to create an IoT application with Espoir without any programming. This week, I have a follow-up guide, IoT irrigation with Espoir. It covers the fabrication and configuration...

Connect the Chirp to your LaunchPad
Log from Magnificent Moisture Management
Now that you've hopefully ordered and received your chirp! sensor ;), it's time to connect it to your LaunchPad. The basic process is very simple, as the Launchpad acts the I2C master and the chirp! is an I2C slave at address 0x20. So let's look at the...

Phase II: Additional Testing
Log from AGI-ESP8266
Okay, a few quick updates:- I've gotten a DS18B20 Temperature sensor working with the ESP8266 Huzzah- I've gotten the deep sleep function on the ESP8266 Huzzah working as well, I am currently running long term tests to determine how long the weather...
