We make durable wireless sensors. Our sensors connect via Wi-Fi or long range LoRaWAN. All of our sensors are IP67 - water and dust proof. All sensors can be monitored from the Zynect App. Our suite includes:Thermote: Temperature sensor that monitors -77°F to 257°F (-55°C to 125°C)Thermote-X: Ultra low NIST traceable temperature sensor that monitors -328°F to 392°F (-200°C to 200°C).Soilmote: Soil moisture sensor that monitors 0% - 100% volumetric water content.
