IoT applied in Agriculture with Micro:bit

IoT technology in Agriculture

IoT (Internet of Things) technology can be used in agriculture to improve crop yields, reduce costs, and increase efficiency. IoT devices, such as sensors, cameras, and drones, can be used to gather data about crop growth, soil conditions, and weather patterns, which can then be analyzed and used to make more informed decisions about planting, irrigation, and fertilization.

Some examples of how IoT can be used in agriculture include:

  • Precision Agriculture: IoT-enabled sensors can be used to gather data on soil moisture, temperature, and pH levels, which can be used to optimize irrigation and fertilization. This can help to reduce water and chemical usage, and increase crop yields.
  • Crop Monitoring: IoT cameras and drones can be used to monitor crop growth, detect pests and diseases, and identify areas that need attention. This can help farmers to take action more quickly and make more informed decisions about crop management.
  • Livestock Monitoring: IoT sensors can be used to monitor the health and well-being of livestock, including temperature, heart rate, and movement. This can help farmers to detect potential health issues early and take action to prevent them.
  • Weather Monitoring: IoT sensors can be used to gather data on weather patterns, such as temperature, precipitation, and wind speed, which can be used to predict future weather conditions and make more informed decisions about planting and harvesting.
  • Automation: IoT technology can be used to automate tasks such as irrigation and fertilization, which can help to reduce labor costs and increase efficiency.

Overall, IoT technology in agriculture can help farmers to increase crop yields, reduce costs, and increase efficiency. By gathering data on soil, weather and crop conditions, it can help farmers to make more informed decisions and take more precise

For example, data from temperature, humidity and soil moisture sensors can be used to optimize irrigation and fertilizer use, increasing crop yields and reducing costs.

Overall, ThingSpeak provides a powerful tool for collecting, analyzing, and visualizing data from devices like the Micro:bit, making it an useful option for agriculture and other IoT applications.

Purpose of this project:

IoT technology can be used in agriculture to improve crop yields and efficiency. The Microbit is a small, low-cost computer that can be used to collect data from sensors and control devices on a farm. This data can be used to optimize irrigation, fertilizer use, and other aspects of crop management. Additionally, the Microbit can be used to control and monitor various devices on the farm, such as pumps and valves, to improve efficiency and reduce labor costs. Overall, the Microbit can be a valuable tool for farmers looking to increase yields and reduce costs through the use of IoT technology.

This project describes the application of IoT (Internet of Things) in agriculture. In this environment we take measurements of the humidity of the soil of a plant.

Monitoring of the parameter around this process (information provided by the soil sensor) is done using open source tools and resources such as Micro:bit and ThingSpeak. We read the sensor data in real time on the internet through a web page and also on the graphs in ThingSpeak.

This work is carried out using Micro:bit connected to an ESP8266 module which will send all the information via WIFI concerning the environment of our plant, to ThingSpeak.

Soil moisture sensor

A soil moisture sensor is a device that measures the water content in soil. It can be used in agriculture, gardening, and landscaping to monitor soil moisture levels and determine when to water plants or crops.

There are different types of soil moisture sensors, but most work by measuring the electrical resistance or capacitance of the soil. When the soil is dry, the electrical resistance is high, and when the soil is wet, the resistance is low. Some soil moisture sensors also measure the dielectric constant of the soil, which changes with the water content.

Soil moisture sensors typically have two electrodes that are inserted into the soil. The electrodes measure the electrical resistance or capacitance of the soil and send a signal to a microcontroller or other electronic device. The microcontroller can then interpret the signal and determine the moisture level of the soil.

Soil moisture sensors can be used in agriculture to optimize irrigation and fertilization, reducing water and chemical usage, and increasing crop yields. They can also be used in gardening and landscaping to determine when to water plants.

They can be connected to Microbit or microcontroller board and integrated with IoT technology to transmit the data to a remote server for monitoring and analysis, and can also be integrated with actuators such as valves and pumps to automate irrigation.

In summary, a soil moisture sensor is a device that measures the water content in soil.
