Hobo S-VIA-CM14 – Onset
Voltage input adapter, compatible with the USB data loggers stations or with the web-based monitoring systems for remote communication
The 12-bit voltage input adapter interfaces with sensors providing 0-5 VDC signals to act as a smart sensor with compatible data loggers. This adapter features both a non-switched input and a battery-saving switched input that extends the life of external batteries. It also provides a trigger signal for controlling power to attached external sensors, while offering digital filtering which improves measurement accuracy with 32 readings/sample.
The digital filtering improves the measurement accuracy and measurement averaging over logging interval further enhances the accuracy. This is a plug-and-play smart sensor, who is compatible with RX, H21, H22, and U30 loggers (stations). The Hobo RX3000 and U30 stations have room for two adapters and if you use this sensor with the Hobo USB Micro Station and/or Hobo MicroRX Station than it requires the smart sensor consolidator box (S-ADAPT-6) with an extension cable.
This sensor operates in indoor and outdoor environments and the S-VIA-CM14 sensor supports the following measurement: DC voltage.
