WARNING Calibration of all new unit should be checked by exposing the sensors to a known gas concentration before putting the instrument into service. For maximum safety, the accuracy of reading of the iSens should be checked every three months.
1. INTRODUCTION iSens uses an electrochemical sensor to detect oxygen and toxic gases and it is powered by 2 x 3,6 V lithium batteries. The sensor reading is sent via LoRa to the control panel. LoRa provides long-range communications: up to one kilometre in urban areas, 5 in industrial area and up to 14 kilometres in open areas (line of sight).
For maximum safety, accuracy iSens should be checked by exposing the sensor to a known concentration of gas over a period. Sensotran recommend doing it at least, every six months. V1.0 Sensotran, s.l – 17/04/2024...
Physical Description The design of iSens makes it easy to place and connect at a fixed location to monitor gas. ATTENTION To prevent ignition in explosive atmospheres, instrument cannot be installed on hazardous area. V1.0 Sensotran, s.l – 17/04/2024 Page 4...
3. INSTALATION The design of the iSens allows it to be mounted on a wall or on a pipe clamp. In a wall, make 2 holes 131 mm apart. V1.0 Sensotran, s.l – 17/04/2024 Page 5...
4. STARTING UP THE UNIT iSens is supplied with all the configuration as per your request and do not need any configuration for operation. However, if you need to change any internal parameters you can access them throw the iSens APP.

- Battery: Percentage of remaining battery. - Last calibration: Last calibration date. - Last reading: Last sensor reading transmitted. - Temperature: Temperature in ºCelsius. - Relative humidity: Relative humidity in percentage. - UID: Unique identifier. V1.0 Sensotran, s.l – 17/04/2024 Page 7...
(PN#IS-001-02), CO must be 2 (PN# IS-002-02), Cl2 must be 6 (PN#IS-006-02), … - ID: Channel identifier. Each iSens must have a different ID in the same PAN. That ID should be the same than the one configured on the GasVisor channel configuration.
3. The ZERO button on the APP displays the time remaining to perform the zero calibration. II - Span calibration 1. Connect the Standard calibration gas to the iSens sensor using the calibration adapter and open the valve to let gas flow. V1.0 Sensotran, s.l – 17/04/2024...
5. Close the gas valve. Note: You can read the iSens data by approaching the mobile phone close to the iSens and if the calibration date has been updated it means that the calibration has been successful. 7. TROUBLESHOOTING - The controller panel does not read data: Check that ID and PAN are properly configurated.
