Telemetry2U's Aluminium Temperature Buffers are meticulously designed to emulate 30ml of water. By adding a thermal mass to a temperature sensor, these buffers effectively minimize the risk of false alarms caused by transient temperature fluctuations in cold storage environments. Crafted for endurance, they are impervious to corrosion and leakage, ensuring a lifetime of reliable performance.

The DS18B20 is a waterproof digital temperature sensor is designed to work with the LSN50 v2, but is suitable for many other products requiring a simple temperature measurement. Supplied on a 1.5M lead and bare wires, connection to the LSN50 is made simple via the on board terminal blocks.

The FT232RL USB-TTL Break out Board is a handy tool used to access the terminal on all nodes supplied by Telemetry2U. The terminal is used to both configure the nodes via well documented AT commands and in some cases, upgrade the firmware. A USB -A to Mini USB is required for connection to a PC. The FT232RL has an on board regulator delectable for 3.3V or 5V.

This SHT20 I2C temperature & humidity sensor is equipped with a waterproof probe. It comes with the 4C CMOSens® SHT20 temperature & humidity sensor chip and the probe has gone through dual waterproof protection testing. It's well suited for connection to the LN50v2

This programmer/debugger will allow users to upgrade or modify the firmware in the LDS01 door/window sensor, LWL01 leak sensor and the LHT65 Temperature and Humidity sensor. Instructions for upgrading the firmware can be found in the appropriate manuals. Although all products purchased from Tememetry2U will be upgraded to the the latest firmware before shipment, new firmware may be released at a later date to fix bugs and add features. As well as being compatible with Telemetry2U products, this programmer will work with all STM8 and STM32 processors.

This UPS will work with LoRaWAN Gateways supplied by Telemetry2U and will provide back-up power for a few hours in the event of main supply power failure. Please note that this item contains Lithium 18650 Battery, thus is can only be shipped by Road Freight.
