An Introduction to SensMit Technology and the iDUS Controls Maker Program October 2017
SensMit Technology • SensMit is a compact, battery-less, solar- powered, 24/7/365 system for in-field real-time measurement of soil and environmental conditions. • Sensor data from each node is routed through an ISM band radio-mesh network to a gateway where it can be uploaded to the web and or used locally. • SensMitWeb is an AWS-hosted application that publishes SensMit data.
SensMit Array Network Aggregates Data • Relay and End nodes collect data from up to 8 sensors each. • The S5 system is a Next-Gen ISM SensMit that has ‘best in class’ communication +/- 3000 feet between devices. • S5 supports 60 direct-to-base End nodes and 8 Routers and 8 additional End nodes per router so a maximum of 124 nodes. • Data is sent to the Base device either directly or via Relay nodes. • The Base then sends all Node information to a Gateway device; a Cellular version is used in this example.
Cell Gateway ‘Mule’ for testing connectivity The ‘Mule’ tests the Cell Modem’s communication with local cell towers to determine if a location has reliable communication. Green is the RSSI in the example it varies from 85% to 30%. The higher the better Blue is the Bit Error Rate the higher the number the higher the rate of data loss Grey is the Total Errors the modem has experienced delivering its data
SensMit Web – Data Publishing • Gateway devices send the data to the SensMitWeb site so that the users can see it in real-time. • SensMitWeb allows users to map the location of their nodes. • At a glance users can see the status of their sensors and access valuable diagnostic information. • By clicking on the sensor icons, users can see the latest sensor readings that each node had.
SensMitWeb Data • Users can see the data from each Node in their Mesh. • Data can be seen on three different tabs; Moisture, Temperature and Diagnostics. • Users can select what types of sensor information to see and what time frame to look at. • Users can set their Nodes to send them alarms when sensor readings fall above or below specified thresholds.
API – Data Publishing • Pull and Push APIs are available • Well documented • Custom ‘push’ systems on request • Simple to directly integrate data with enterprise software or Farm Information Systems

Greenhouse Sensor Suite • SensMit devices can operate with the light energy created by grow lights even in a 12 hours on/12 hours off setting. • Supports up to six different sensor types. Up to four of each sensor type can be attached. Allowing for up to 24 sensors to be installed. • Current supported sensor types include: Tensiometers, Vegetronix’s VH200, Electro- Conductivity, Plant Scan, and Soil Temperature • Sensor can gather readings in multiple grow mediums including: Soil, Rockwool and Coco Coir.
Usin ing the Greenhouse Sensor Suite in in a Grow Room • The SensMit device and the Greenhouse Sensor Suite can operate from energy given off from the grow lights. • One Greenhouse Sensor Suite could be used for a tray of plants as the sensor cables could be set up at up to 4 different intervals. • SensMit supported sensors can work in many mediums such as Coco Coir, which is being used in the picture.
