Endless Applications

Cold Chain Monitoring

Our sensors are designed to handle the harshest RF environments, including the operating world of refrigerators, cold stores, and freezers. Monitor and protect your products from spoiling wherever you are with temperature and humidity sensors. Maintaining optimal temperature of your food or pharmaceutical supplies is crucial in preventing costly spoilage. Laird Connectivity’s wireless temperature monitoring solutions provide a reliable and affordable way to ensure your coolers and freezers are working properly, providing automated, real-time monitoring and reporting with digitized capture and reporting of operational activity.

Deliver mission critical wireless M2M communication networks tailored to the needs of agricultural applications like greenhouses and crop storage that require specific environmental conditions. Crops can be lost if the mixture of temperature and humidity are incorrect. Working with Laird Connectivity means saving time and resources. Streamline workflow efficiency, increase productivity, and avoid perishable product loss or damage across all of your assets, wherever they are. Automated systems track conditions for you and send real-time alerts before small issues become big, expensive problems.

Industrial Heating and Cooling

Maintaining specific temperatures can sometimes put heating and cooling systems to the test. Heating and cooling units are constantly at risk and can be costly to repair if failures are not caught in time. Laird Connectivity’s IoT sensors provide a solution for monitoring multiple aspects of HVAC systems and will alert you of any issues in real-time.
