Wireless Control

Sense IoT wireless control units contain two separate relay switches allowing for individual control through the Sense IoT online sensors portal. The control unit relays can be switched on/ off manually through the software or automatically by any wireless sensor notification assigned to a single sensor or group of sensors when a specified condition is detected.

Principles of Operation

The Sense IoT control unit has two separate relays that can be toggled on/off at will by either: (a) the Sense IoT portal; (b) any device that triggers a notification on the same network. Four LED indicators let the user know if the device is powered on, communicating with the online system and the status of each relay.  The user can manually turn a relay on or off through the Sense IoT software. Manual changes are either: (a) temporary based on a set duration  (ex. activate the relay for 10 minutes then return to the default state); (b) perpetuated indefinitely until overridden. Each of the units two relays can also be controlled automatically by any wireless sensor or group of  sensors. Automatic relay switching can be triggered by setting the control parameters in a  sensor notification from the system. The user can set the default state of each relay to on or off and user defined messages from sensors will cause the relay unit to switch to the non-default state. The relay switches back to its default state when the  condition is no longer met. Example Use: If a water sensor detects water at a certain level in a sump pit, the relay will switch ON, activating the pump. When water is no longer detected, the relay will switch OFF, deactivating the pump motor. Sense IoT sensors offer 3 to 4 times the range of standard sensor platforms, extending non-line-of-sight reach to an exceptional 350 meters through walls (12-14 walls typical). Using Frequency-hopping Spread Spectrum (FHSS) also allows Sense IoT sensors to have better interference immunity from other wireless devices. Superior power management provides Sense IoT sensors with almost twice the battery life of standard wireless sensors.

• Coin cell sensors typically last 3+ years.
• AA and Industrial sensors typically last up to 12+ years.

Sense IoT products employ Sense IoT new Encrypt-RF® Security (256-bit Diffie Hellman key exchange and AES-128 CBC encryption for all sensor data messages), so security is maintained at all communication points from sensor to gateway, gateway to software, then back again. Integrated on-board data storage allows Sense IoT sensors to store data messages if communication to a wireless gateway is disrupted (power outage, Internet outage, or out of range). Messages that can’t be delivered will be time-stamped and stored in memory (up to the last 512 messages) until communication with the gateway is restored, at which point the messages will all be transmitted. Over-the-air updates allow Sense IoT products to be updated remotely if new fixes or features become available. The standard version of this sensor is powered by two replaceable 1.5 V AA sized batteries (included with purchase). This sensor is also available with a line power option. The line powered version of this sensor has a barrel power connector allowing it to be powered by a standard 3.0 - 3.8 V power supply (Included with Line Power option upgrade). The line powered version also uses two standard 1.5 V AA batteries as backup for uninterrupted operation in the event of line power outage. Power options must be selected at time of purchase, as the internal hardware of the sensor must be changed to support the selected power requirements. ^*Actual range may vary depending on environment. ^**Battery life is determined by sensor reporting frequency and other variables
