2.4GHz Wireless Strain Logger (WL-S)

 Introduction

With one differential channel, which include full strain gauge conditioning and programmable
offset, the WL-S is compatible with most types of analog sensor. Fast and extremely versatile,
the WL-S is designed to operate as part of a high speed wireless sensor network.

Featuring 800Hz sampling rates, combined with 16 bit A/D converter, these little nodes pack
A lot of power in a small package. With every logger in the wireless network assigned a
unique MAC address, a single host transceiver(MSP1000) can address 12 of logger.
The bi-direction RF communications link can trigger a sample to be logged from 200meters,
or request real-time data to be transmitted to the host PC for data acquisition/analysis.



The scalable system architecture and programmable sensor interface enables a new generation of
wireless sensor networks.
The WL-S is compatible with a wide range of Wheatstone bridge type sensors, including
strain gauges, displacement sensors, load cell, torque transducers, pressure sensors, accelerometers,
geophones, temperature sensors, inclinometers, and others.

 Switch Operation

You can turn on the ILOG power When do you long time push to the switch

(3 seconds over), or turn off.

• Use to mode method

-Flash saving mode

If you want to using the mode of flash memory save then, you can try push the

switch short time twice and long time once.
◦◦▬Flash memory save mode except to a Bluetooth

-Bluetooth setting mode

Although the ILOG has the Bluetooth default settings(Acceptor mode),
User can do try mode change (Bluetooth acceptor mode or MSP

connect mode).

But we don’t recommend try this mode because suit factory set to user's
situation.
