SPH01-LS LoRaWAN Ground pH Sensor 868MHz with Solar

The SPH01-LS LoRaWAN Soil pH Sensor is an innovative IoT device specifically designed for monitoring the pH level and temperature of the soil in agriculture. With its IP68 certified probe, the sensor is suitable for long-term use in the soil. Thanks to its robust design, the sensor is ideal for outdoor use. This model uses a combination of solar cells and a supporting battery to guarantee optimal performance and longevity outdoors. The measurement is carried out by a solid AgCl reference electrode and a pure metal pH electrode, which deliver precise and stable values. The SPH01-LS uses LoRaWAN technology for extended wireless communication and supports Bluetooth for easy configuration and firmware updates. Each sensor comes pre-installed with unique keys for LoRaWAN registrations, allowing automatic connection to the LoRaWAN server.
