Installation and Operation Instructions for the Wireless Temp/RH or Light Sensor.

Point Six, Inc.

Wireless Temperature/Relative-Humidity or Light

Sensor Model WOWTHL

Installation and Operation Instructions

The WOWTHL wireless temperature Relative-Humidity or Light level sensor transmits a

digital temperature, relative-humidity (or light level) and a unique serial number to a 418

MHz receiver. The WOWTHL is enclosed in a high impact ABS enclosure for direct

surface mounting in the environment to be measured. The WOWTHL is battery

operated.

Application: Apply the sensor to the surface to be monitored with double-sided

adhesive tape. Make sure that the side labeled with FCC ID is visible and away from any

metal surfaces.

Service Function: The wireless sensor has an installation mode switch. A momentary

push of this switch will start the convert/transmit cycles. When new and until this button

is pushed the WOWTHL will not transmit. The WOWTHL will transmit a special

installation status mark in the data packet immediately after the installation/start switch is

pushed. After the start a push of the installation switch will result in the immediate

transmission of temperature, relative-humidity (or light level) ID and installation status

mark.

Battery: A 3.0-3.6 Volt lithium battery powers the WOWTHL wireless sensor. The

battery will last for more than 10 years in the idle state (as shipped from the

manufacturer). The WOWTHL will transmit data for as long as 3 years at a rate of once

each minute once started. The WOWTHL is completely covered with a water resistant

rubber coating to protect the electronics from the environment and condensation. The

user cannot replace the battery. The WOWTHL may be placed in a quiescent state

(battery life greater than 10 years) by holding the installation switch closed for more than

12 seconds.

Page 2 CAUSE UNDESERED OPERATION Wireless Sensor Data Format The Point Six, Inc. 418 MHz wireless sensors require a compatible receiver with the ability to receive, error check and provide RS232 and RS422/485 interface. This document describes the data format provided by the HA8-wow 418 MHz. Receiver.
Page 3 FCC ID: M5ZWOWTHL Bits 0-6 of the MSB contain the RH value in %RH (0-100%). In the case of light level bits 0-6 of the MSB is the relative light level. 2-byte CRC-16 this is the originally received data packet CRC as described above. 1-byte checksum the checksum is a mod 256 sum of all the ASCII character values in the response but does not include the CR...
