Telemetry2U (T2U) offers the Dragino range of LoRaWAN IoT Sensor Nodes. Dragino have been operating since 2010 with a strong focus on open source IoT technology. All Dragino LoRaWAN IoT products are supported and supplied by T2U, however our IoT interface is compatible with a host of other LoRaWAN devices, some of which you can see here. If you have another type of node in mind, please get in touch with us.
IoT sensor nodes used with T2U’s IoT Platform provide a true plug-and-play experience. When nodes are purchased with a 1-off 'T2U node licence', they come ready to go, straight out of the box, no programming or complicated configuration settings required. Users are able to log into their T2U account and start collecting and viewing data immediately. In most cases, installation is neat and simple, requiring no special tools or equipment. Internal batteries provide up to 10-years of operation and remove the need of a separate power supply, saving resources, space, and wires.
T2U takes advantage of LoRaWAN technology to get sensor data to our IoT network servers. LoRaWAN uses a long-range radio link for communications between the sensor node(s) and gateway(s). The gateway converts radio packets into IP packets so the data can travel over the internet to T2U network servers. For this reason, the gateways requires an internet connection either through Ethernet, Wi-Fi, or 4G. Gateways are sold separately from the nodes and must also be purchased with a 1-off 'T2U Gateway Licence' in order to work on T2U the servers.
The Dragino LAQ4 Indoor Air Quality Sensor combines a VOC (Volatile Organic Compounds), eCO2 (Equivalent Carbon Dioxide), Temperature and Humidity sensors all in one package. It is battery operated with an expected life of 7-10 months depending on environmental conditions. It will immediately send an up-link if any sensor exceeds your threshold and it also has a data logging function so you can manually download your data in emergency situations. You can also calibrate the VOC and ECO2 for greater accuracy.

The Dragino LLMS01 is a LoRaWAN leaf moisture and temperature sensor and when used with Telemetry2U, quickly enables a level of smart farming through the Internet of Things (IoT). Leaf Moisture can be important for controlling anything from fungus and diseases to irrigation systems. With T2U, you can be alerted if your leaf's require watering/moisturizing or when there is a dew or they are frozen, helping you optimize growth and general farm management.
The LSE01 is a LoRaWAN Soil Moisture & EC Sensor for Agriculture applications. It detects Soil Moisture, Soil Temperature and Soil Conductivity, and uploads the the via wireless to LoRaWAN Network. .It is designed to measure the soil moisture of saline-alkali soil and loamy soil. The soil sensor uses the FDR method to calculate the soil moisture, with compensation for soil temperature and conductivity.
The Dragino LSPH01 is a LoRaWAN Soil pH and Temperature Sensor. When used with Telemetry2U, it quickly enables a level of smart farming through the Internet of Things (IoT). pH is critical for plant growth, as it influences the availability of essential nutrients and their chemical reactions. The Silver Chloride (Ag-Cl) reference electrode and the pure metal pH sensitive electrode offer high accuracy and stability over the range, with temperature compensation. It can be buried in the soil for long term use, with the battery lasting up to 5 years.
The Dragino LGT92 LoRaWAN GPS tracker offers a low power GPS module combined with a 9-axis MEMS sensor (accelerator, gyroscope and compass). Its primary function is to provide motion detection and up-link the current GPS positions. It also has a emergency button that will immediately force an up-link when pressed. The power for both the GPS module and MEMS sensor are controlled by the MCU to achieve the best energy profile, but the power settings are user configurable.
The LDS02 is a LoRaWAN door/window sensor that detects open/close events and then sends its status it to a LoRaWAN network. The LDS02 is small in size (40 x 15 x 15mm) and is powered by a two standard AAA Alkaline batteries. In ideal LoRaWAN network coverage conditions, the LDS02 transmits up to 70,000 data records to the server for the life of the battery. Poor LoRaWAN network coverage will allow for the transmission of roughly 16,000 data records. The LDS02 product design allows for a battery life between 2 and 10 years. Once finally flat, the AAA batteries are straight forward to change.
Based on the LSN50 Open Source platform, The waterproof (IP68) LDDS75 offers long range connections to LoRaWAN networks.
