HTA series environmental sensor is useful to measure temperature, humidity as well as particulate matters of sizes 2.5 micron and 10 microns. These are useful for traffic junctions, public parks, logistics parks etc to monitor these parameters and maintain integrity of operations.

With availability of RS485 option, we can help integrate the data visibility remotely by deploying third party IoT gateways and AWS.
