HYDAC Lab® HLB 1400 is a multifunctional sensor for online monitoring of the condition of standard oils and bio-oils in industrial and mobile applications.
- HSP Protocol Implementation: Decodes and handles requests and responses based on the Hydac Simple Protocol (HSP) / RS485.
- Request Types:
Id: Retrieves the sensor's identification information.Status: Obtains the current operational status of the sensor.Data: Fetches real-time oil condition data.
- Data Decoding: Requests and responses were captured via a COM analyzer and decoded due to the lack of available online documentation.
- Microcontroller e.g.: ATmega328 (Arduino UNO), ESP32 (ESP32 DevKitC), RP2040 (Raspberry Pi Pico), ..
- RS485 Transceiver: e.g., MAX485 or similar module
- Connections:
- Connect the RS485 module to the ESP32 UART pins.
- Ensure proper termination and biasing for RS485 communication.
- Upon successful communication, the program will retrieve and display sensor data such as saturation level, temperature, dielectric constant, and electrical conductivity.
- Consider integrating with a display or logging system to visualize and store the retrieved data.
