Seeed 101990862 sensor probes with wall mount tube installation and robust IP66 IP68 protection rating
SenseCAP Sensor Probes Catalogue
SenseCAP is a Seeed IIoT product series focusing on wireless environmental sensing applications including smart agriculture, precision farming, and smart city. It comprises hardware products (sensors, data-loggers & gateways), software services (SenseCAP Mate App, SenseCAP Web Portal, open dashboard), and APIs for device & data management. SenseCAP industrial sensor probes are engineered for harsh environments, offering resistance to vibration, chemicals, and gases. They feature high IP ratings (IP66 to IP68) for robust performance, process connections for secure fitting, and data transmitters for industrial instrumentation systems. Some MODBUS RS485 Industrial Sensors are available in two versions: one with hook-up wires for SenseCAP LoRaWAN Data Logger and another with an aviation connector for SenseCAP Sensor Hub 4G Data Logger.
