Frequently Asked Questions
Everything you need to know about our high-precision 7 in 1 soil sensor
A soil moisture sensor measures the volumetric water content (VWC) and temperature in soil using advanced dielectric or frequency domain technology. SunBio's IoT sensor transmits this real-time data via wireless or Modbus RS485 protocols to automated irrigation systems and cloud dashboards.
Unlike basic resistive modules (such as YL-69) that corrode quickly in damp soil, SunBio sensors feature an IP68 weatherproof rating, corrosion-resistant alloy pins, and industrial Modbus RS485 communication built for long-term commercial agricultural deployment.
By continuously monitoring root-zone moisture levels 24/7 and triggering automated push alerts or controller actions, SunBio's IoT nodes prevent over-irrigation and eliminate agricultural runoff, optimizing water usage by up to 40%.
Yes, SunBio soil sensors support standard Modbus RTU RS485 communication, allowing seamless integration with industrial PLCs, microcontrollers like ESP32/Raspberry Pi, and custom IoT gateways.
