Wireless Temperature Sensor M Series with External Sensor

Monitor temperature from your phone or Desktop Create temperature alerts Use temperature to trigger automation Pair of AA Batteries lasts over a year, Batteries Not Included. Powerful transmitter can penetrate walls and floors and up to 1km line of sight Configured to transmit a temperature reading every 5 minutes (configurable). Out-of-box temperature monitoring solutions available   Can be interfaced with many IoT systems (e.g. Blynk, Home Assistant, Adafruit IO, ThingsBoard, PrivateEyePi, MQTT, Amazon AWS IOT, Google Cloud IoT).   Tutorials: Temperature monitoring solutions Wireless Temperature Sensor Tutorial Test temperature sensor PrivateEyePi Alarm System JemRF Documentation Technical Specs: AA Housing with On/Off Switch Temperature Sensor is DS18B20 for high accuracy and repeatability. DS18B20 temperature sensor is used to detect the temperature Measures temperatures from -55°C to +125°C. Fahrenheit equivalent is -67°F to +257°F, ±0.5°C accuracy from -10°C to +85°C DS18B20 is connected to sensor via 1 or 2 meter water proof cable. All devices are based on the high-performance RF transceiver based on the market-leading CC1100 SOC. Wide operating voltage range of 2-3.6V makes the devices 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. Driver-less installation. All the devices are highly configurable through the serial port or over the air using the LLAP messaging protocol specified in the manual.  Base station communicates through serial port (TTL UART). Communicates in ASCII clear 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. Virtually unlimited amount 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 be use for long periods of time (up to 1 year depending on transmission rates). Supports 6 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 micro-controllers like Raspberry Pi and Arduino : Tx, Rx, GND, 3V3. Battery monitor to keep track of power consumption.
