Sensor Probes - Libelium Waspmote Plug & Sense! Series Technical Manual

Sensor probes

6. Sensor probes
All sensing capabilities of Waspmote Plug & Sense! are provided by sensor probes. Each sensor probe contains one
sensor, some necessary protections against outdoor environmental conditions and a waterproof male connector.
The standard length of a sensor probe is about 150 mm, including waterproof connector, but it could vary due to
some sensors need special dimensions. Weight of a standard probe rounds 20 g, but there are some special cases
which this weight can rise.
Sensor probes are designed to be used in vertical position (with sensor looking to the ground). In this position, the
protection cap of each sensor probe is effective against bad weather conditions.
Each model has six dedicated sockets to connect sensor probes. They are located in the sensor side, as shown
below. Each socket has a protecting cap. When one of the six sensor connectors is not used, be sure the cap is
screwed to protect the connector.

Each sensor socket is identified by a letter from A to F (see picture below). The user should understand that each
sensor probe should go in a dedicated socket, due to each sensor has different power requirements (current and
voltage levels), dedicated circuitry, etc. So please see corresponding section about where to connect each probe.
Always be sure you connected probes in the right socket, otherwise they can be damaged.
Never connect a sensor not provided by Libelium to any of the sensor connectors. The electronics system inside
can be damaged and the warranty will be automatically void.
