Wireless Switch - No Sensor

RF ID

Quantité

The wireless switch can be used for monitoring doors and windows. This option does not include the Door/Window switch and can be connected to your existing door/window reed-style sensors. It is small (1” x 1” or 2.54cm x 2.54cm) and can be installed discreetly. Battery life is around 1 year, depending on the number of transmissions. Rugged yet elegant cream plastic case allows the sensor to be deployed both indoors and outdoors, and, if sealed with silicone, could be water-resistant. It can operate in request/reply or publish mode using an external power source. When asleep, it is awoken by a change in the external switch (i.e., open or closed) to send readings. If powered externally, then the device can operate in a fully awake mode and can respond to requests for switch state in a request/reply fashion. The device will also transmit switch state changes when in fully awake mode.

Optimize battery life

Tested at 288 (144 door open/door close) messages per day for 1 year on one battery.

If you are using this sensor for doors and windows that are usually closed, then use a Normally Closed switch.

If you are using the sensor with a door or window that is usually open, then use a Normally Open switch.

Technical Specs:

All devices are based on the high-performance RF transceiver based on the market-leading CC1100 SOC.
A wide operating voltage range of 2-3.6V makes the devices well-suited for battery power.
Current consumption: RX: 16.2 mA, TX: 15.2 mA. Deep Sleep: 0.005Ma (0.5 µA).
Up to 1KM line of sight. Short range (30M) penetration of walls and floors.
128-bit AES encryption security.
Driverless installation.
All the devices are highly configurable through the serial port or over the air using the LLAP messaging protocol specified in the manual.
The base station communicates via a serial port (TTL UART).
Communicates in clear ASCII text, making it very easy to exchange data between devices over the air.
Supports point-to-point, point-to-multi-point, multi-point-to-point, and multi-point-to-multi-point.
A virtually unlimited number of devices can be deployed—99,999 Personal Area Network ID’s, 10 channels per frequency and 7,744 Device ID’s per network.
Super-low power consumption allows devices to run on a coin cell battery for extended periods (up to 1 year, depending on transmission rates).
Supports six frequencies (433 MHZ, 915 MHZ (default US & Canada), 868.3 MHZ (default Europe), 868 MHZ, 903 MHZ, 315 MHZ)
10 channels per frequency.
4 pins for communicating with external microcontrollers like Raspberry Pi and Arduino: Tx, Rx, GND, 3V3.
A battery monitor to keep track of power consumption.
