Whisker.Block

, Dry Contact & 4-20 mA Analog Input
D6 Labs Whisker-Block_3qtr-View_01
General Description
A long-range, 900 MHz, wireless sensor in a durable, transulcent
IP67 case with LED feedback, including two external input channels
for connecting a dry contact sensor and a 420 mA analog sensor. The
sensors are prewired to an included wire bundle, which connects to
the Whisker.Block
®
via an M8 connector. Also included is an internal,
on-board, thermistor with +/- 1°C accuracy. By default, readings are
taken every five minutes and battery life will last over ten years on
the included battery pack.
Power
This Whisker.Block
®
can be powered internally using a 3.7V, 5.2A-H
LiThCl battery pack (10+ years of service life) or 8-24V DC through
Connector 1 pin 1. Select variants are equipped with an internal
5V/18V sensor power supply that can provide up to 30mA to
external sensors; this is available on pin 1 on both connectors when
battery power is used and pin 1 of connector 2 when external DC
power is used.
Range
In an unobstructed, outdoor line-of-site environment, the sensor
should be able to communicate for more than
.5 miles
assuming a
receiving antenna elevation of
10 feet
. If the receiving antenna is
raised to
20 feet
or more, the range should increase to more than
1 mile
. Range performance will degrade if the internal antenna is
used; maximum range is achieved with the external antenna.
