Monitoring the temperature of compost offers insight into the maturity and management of piles. Consistent and effective management allows for a solid feedback loop in regards to when to turn, maintaining optimal conditions, when a pile is ready for use, and microbial activity.
While compost temperature management is currently a manual process, Leveltec is working with their partner Tekon to offer a turnkey digital solution for this essential industry.

Process

Composting is a slow and natural process that turns organic waste into fertilsers. Temperatures are recorded manually by workers to monitor each stage of the composting process.

Objective

Automatically monitor, record, and notify the operator about temperatures during all stages of composting process and to do this continuously without installation of probes with long cables. Visually display the analysis of the fermentation process through a real time data logger to ensure compliance and alert the operator of abnormal conditions.

Solution

  • Wireless Probe and Transmitter in the compost pile
  • Data periodically sent to the Gateway WGW420
  • PIM101 IoT module to interface with Tekon IoT Platform on the cloud
  • Data record, visualization, analysis and alarms with Tekon IoT Platform

Technical Details

How does the wireless temperature monitoring work?
Each measuring point consists of a temperature probe and a wireless transmitter. The temperature probe can be composed by 1 or 2 measuring points, according to the customer’s requirements. The wireless transmitter, installed on top of the probe, can be powered in two ways:

– Solar panel: powered by solar energy that charges rechargeable batteries, existing inside the transmitter. The batteries can also be rechargeable via a mini USB port inside the transmitter.

– Primary batteries: lithium/alkaline battery pack for direct supply, inside the transmitter. It can be used batteries rechargeable externally.

QUICK, RELIABLE AND SECURE
Eliminate the manual process of measuring and recording temperatures from the composting process. Using Tekon IoT Platform data analysis tool, you can quickly access to data from any device and place. Reduce the risk of accidents at work, avoiding contact with the fermentation atmosphere. Monitoring is done remotely and continuously.

WIRELESS MONITORING
Our composting solutions work under a dedicated network to secure the data collected. All the processes can be monitored in our Tekon IoT Platform, working local or on cloud.

TEKON IOT PLATFORM
Tekon IoT Platform is a solution for data visualisation and analysis, fully developed by Tekon Electronics. Through this tool, you can consult the data of your probes and processes, at any time, from any device. You can configure alerts that focus on temperatures and other variables in the monitoring process, which will send you notifications by email or SMS, whenever the process reaches or exceeds the defined values.
