Press’o User Guide 1 INTRODUCTION This document describes the usage of the Press’o sensor. It is necessary to read the LoRaWAN Sensors Behavior on Public LoRaWAN Networks guide and the Application Layer Description guide in prerequisite for all generic information or to have more details. 1.1 G ENERAL DESCRIPTION The Press’o sensor manages two different power supplies, one is external and energizable in 9-15V the other one is internal on a disposable A 3.6V battery.
Press’o User Guide 2 ELECTRONIC To select the 4-20mA mode or the 0-10V mode, it is necessary to put the switch on the right position. 2.1 4-20 MA In the 4-20 mA mode, the V+ (power supply of the external sensor) is powered on during 120 ms at 10 V. Presso 4-20mA sensor + - 10V V+ M/Vshield [shield] V 2.2 0-10 V In the 0-10V mode, the V+ (power supply of the external sensor) is powered on during 120 ms at 14V with a max current of 50mA.
Press’o User Guide 2.3 KNOWN COMPATIBLE PRODUCT Press’o sensor is compatible with the set of product: CTE / CTU / CTW8000...CS from First Sensor.

Press’o User Guide 4 HUMAN MACHINE INTERFACE The Press’o has a buzzer that allows it to “communicate” with the end-user. The link between the sounds it makes and the sensor status can be seen in the array here below. A reed switch (or magnetic switch) is available. It is possible to use a magnet to activate it and makes specific actions on the sensor (Switch off, switch on, Re-associtation…) described in the LoRaWAN Sensors Behavior on Public LoRaWAN Networks guide.
Press’o User Guide 5 APPLICATIVE LAYER The Press’o device is a sleepy Class A device. It implements “Analog Input” clusters, associated to their Inputs.
