Greenhouse Monitoring System Using RC1

Lately in my greenhouse, the plant was infected with fusarium mycotoxins due to high humidity and temperature. Humid conditions also increased the proliferation of weeds, and weed biomass increased with increasing temperatures. So I decided to make this project to learn how to monitor the temperature, humidity, light level in my greenhouse using RC1 to improve my plant's health. 

In this instructable, we will build and code a mini greenhouse monitoring system by collecting the light, temperature, humidity, and soil moisture values over all these sensors. The data obtained through the greenhouse system can be monitored through the LCD in RC1.

1. TekTech RC1 + USB wire
2. Humidity sensor
3. Soil Moisture sensor
4. 6 Jumper Wires
5. Download APP (Windows Only)

The RC1 has light and temperature sensors. We will integrate two other sensors to measure the humidity and soil moisture. All sensors will be programmed as inputs.

The buzzer will be programmed as output.

The temperature sensor returns measurements in Celcius.

The light sensor returns intensity %. It can vary from 0% - 100%

The soil moisture sensor measures the water content in the soil

Your mini monitoring system has to update the user with the temperature, light intensity percentage.

The data will show automatically by scrolling the information on the RC1 display.

In case of the acceptable range of the sensors values is exceeded, the buzzer will beep.

Accurate measurement of soil water content is essential for applications in agriculture - where the under- and over-watering of soil can result in ineffective or wasted resources.

I used the capacitive soil sensor, I tried to take different readings in different cases ( moist & dry ) using this code.

I used the dash board to show the readings

Its time to operate your project

1. Open The App
2. Connect RC1 to the computer using a USB
3. Upload your code using the App

Now you can demonstrate the values of 4 sensors on RC1 display

• Can you improve this system to control all elements in the greenhouse?

Add a pump to your system and control the amount of water depending on the plant's needs.

• Can you evaluate how this project effect estimating crop production in greenhouses?
• You can apply the same concept to hydroponics, sandponics, and aquaponics systems?
