SCS-3 Specifications

Specifications for Conserv's SCS-3 Sensor

Conserv's SCS-3 Smart Collection Sensor is designed specifically for collection care use cases.  It measures visible light levels (including UV for SCS-3-5 and above), temperature, humidity, and movement.

⚠️ Note: this article is for the SCS-3 sensor. The sensor's version can be identified by the label on the back of your sensor. For the technical specifications for SCS-1, click here. ⚠️

Safe handling instructions

As Conserv manages your subscription and your data is automatically transmitted to the Conserv platform, you should not need to interact with your sensor after initial setup.

In rare instances, you may need to replace the batteries in the device. In these instances, only use batteries provided by Conserv. Make sure to follow the symbols marked on the enclosure to properly insert the batteries in the correct orientation.

After three years, Conserv will replace your sensors as part of your subscription. We will ask you to return your old sensors to us so we can refurbish them or dispose of them safely.

Warning: While the sensor may be both operational and functional at very low (freezing) temperatures, please be aware that this sensor is not waterproof and it has not been designed to withstand condensation. Condensation caused by taking the sensor in and out of freezing conditions may damage the internal components. If you wish to use a sensor designed for freezer conditions, we suggest you look into our cold sensor instead.
