Both TX and RX modules are battery powered. TX module includes a conductivity sensor, which can detect body fluids like urine and blood. The RX module includes a piezo beeper for alarm generation. Both TX and RX modules operate in power down mode under normal condition. TX module comes out of power down mode and transmits an RF signal when its associated body fluid sensor becomes wet. This RF signals causes the RX module to come out of power down mode generating alarm condition. Each TX module transmits its own unique ID under wet condition. The RX module can be configured for a particular TX module. 1.1Audience This document is intended for engineering and management staff of Anzacare. 1.2Status The status of this document is draft. 2System architecture Following block diagram indicates the main building blocks of the Anzacare Wireless Body Fluid Detecting Alarm. 1 TX module 2 RX module Figure 2-1: Anzacare Wireless Body Fluid Detecting Alarm Block Diagram 2.1TX Module TX module uses AT86RF401E microcontroller, which belongs to Atmel’s AVR series RISC family. This microcontroller has on chip UHF transmitter. The microcontroller can operate from 2Vdc and consumes less than 0.5uA in power down mode. The microcontroller is in system programmable (ISP). Microcontroller has 6 general purpose input output (I/O) pins. One of the I/O pin of the microcontroller is connected to body fluid sensor via a signal conditioner. Signal conditioner block converts the body fluid sensor’s output compatible to microcontroller. The microcontroller and the signal-conditioner operate from a 3V lithium battery. A reed switch controls Battery power to the TX module. 2.2RX Module The RX module uses ATTINY13 microcontroller, which belongs to Atmel’s AVR series RISC family. The microcontroller can operate from 1.8Vdc and consumes about 0.1uA in power down mode. The microcontroller is in system programmable (ISP). The microcontroller has 6 general purpose input output (I/O) pins. The RX module uses Micrel’s MICRF009 chip as UHF receiver. This UHF receiver chip operates in duty cycle mode to conserve power. In the power down mode receiver chip consumes about 0.15uA current. The receiver chip’s output is connected to the microcontroller’s I/O pin. One of the microcontroller’s I/O pin drives the piezo driver to generate the alarm. The RX module can be configured to a particular TX module using the learn button. Voltage booster is required to power the receiver chip and the piezo driver. TX module is powered from a 3 volts lithium battery. The ON-OFF switch is provided to disconnect the battery from the RX module. The magnet in the receiver case is used to operate the reed switch on the TX module. 2.3Functional Description The cases for TX & RX modules are designed in such a way that the TX module can sits on RX module when the unit is not in use. In this position the RX module’s case- magnet operates the reed switch on TX module, which puts the TX module in off state. The TX module’s power is turns on when it is not sitting on the rest provided by RX module. In power on state TX module conserves power by putting the microcontroller in power down mode. Under wet condition body fluid sensor activates microcontroller’s I/O pin. This causes the microcontroller to come out of power down mode and send an RF signal. The transmitted RF signal includes a 24 bit unique ID for that particular TX module. After the RF transmission the microcontroller on TX module once again enter power down mode. The RX module receives the transmitter signal. The UHF receiver chip passes the received 24-bit ID to the microcontroller. Receiver microcontroller compares this ID with the stored ID. The RX microcontroller turns on the piezo alarm if IDs match. 3 Operating Instructions 1 TX Module 2 2) RX Module Figure 3-1: Anzacare Wireless Body Fluid Detecting Alarm 3.1TX Module The case magnet of the RX module will operate the reed switch on the TX module when the TX module is kept in the rest position provided on the RX module. Thus when the TX module is placed over the RX module as shown in the picture above the TX module’s power will be cut. On the topside of TX module there are two conductive plastic electrodes. Following steps should be followed for testing the TX module. 1. Lift the TX module from the top of RX module. This will turn on the TX module 2. Use a wet tissue paper to short the top conductive pl…

Both the TX and RX modules are battery powered. The TX module includes a conductivity sensor, which can detect body fluids like urine. The RX module includes a piezo beeper for alarm generation. Both TX and RX modules operate in power down mode under normal conditions. The TX module comes out of power down mode and transmits an RF signal when its associated body fluid sensor becomes wet. This RF signal causes the RX module to come out of power down mode generating an alarm condition. Each TX module transmits its own unique ID under the wet condition. The RX module can be configured for a particular TX module. 2 Operating Instructions Picture 2-1: Anzacare Wireless Body Fluid Detecting Alarm 2.1 TX Module When the TX is mounted on the RX module a magnetic switch disconnects the battery in the TX unit. Thus, to ensure maximum life for the TX unit it is recommended that it be mounted on the RX unit when not in use. This is indicated in the picture above. On the topside of TX module there are two conductive plastic electrodes used as a fluid sensor. The following steps should be followed for testing the TX module. (NB. This test assumes that the RX has been trained to the TX. See section 2.4) 1. Clean and dry the TX electrodes with a dry tissue-paper 2. Lift the TX module from the top of RX module. This will turn on the TX module. Ensure that the RX module is switched on. 3. Use a damp tissue paper to short the top conductive plastic electrodes. This will activate the TX module, which sends an RF transmission to the RX. TX Module RX Module Power Switch Learn Button Electrodes Piezo Beeper South Pacific Electronic Design Associates Limited 2006 Revision 1.0 VS Anzacare Wireless Body Fluid Detecting Alarm - Users Guide Page 4 of 5 4. The RX module that is configured for this TX module will enter into the Alarm generation mode. 5. To repeat the trigger sequence clean the TX electrodes with a dry tissue-paper and start again from step three. The TX will not operate again unless it is completely dried. 2.2 Low Battery condition The TX module’s battery is not replaceable. The low battery condition of the TX module is indicated to the user by an intermittent alarm tone from the RX. Under low battery condition the user needs to replace the TX module. Note: When not in use, the TX module should be on the RX module as shown in the picture 2-1. This will give a longer battery life for TX module. 2.3 RX Module The RX module is shown in Fig. 2.1. It has a power on-off switch, a learn push button to configure the RX module and a piezo beeper. The following steps will test the RX module. It is assumed that the RX module is previously configured for the TX module (See section 2.4). 1. Switch on the RX module by moving the power switch position from “0” to “1”. 2. A short burst of beeps after power on indicates that the RX module initialisation is successful. 3. For proper operation of the RX module a five second wait period is necessary. This allows the UHF receiver chip to stabilise. 4. Now the RX module is ready for reception from the TX module. Follow the procedure in Sect. 2.1 to trigger the RX. 5. The RX module enters into alarm mode for 2 minutes. However, the alarm can be stopped at any time by operating the power switch on the RX module. 2.4 RX module configuration The RX module enters into the alarm condition only if it finds a match between its locally stored ID and the ID received from the RF signal. In the RX module configuration process one can modify the locally stored ID of the RX module using the learn button provided on the RX module. The following steps configure an RX module to a particular TX module. 1. T…
