Sensor probes
5.1. Sensor probes types
Libelium provides many different sensor probes depending on what is going to be measured. This section describes main
features of each type. If further information is required, please refer for the corresponding sensor board guide available on
.
Standard Type
This sensor probe is the most common. Sensor is placed inside a plastic cylinder acting as a protection against rain and water,
but allowing sensor interact with environment to measure necessary parameters.
