Analog Sensor Board

The Analogue Sensor Board allows the connection of 8 analogue devices with voltages of 0..4V

** Attention: Your OpenSprinkler 3/3.2 needs a firmware update so that it can recognize the board! (see below) **

** NOT for OSPi !!! But you can use the analog ports from the OSPi Boards!

As an app for your smartphone, search for ‘OpenSprinklerASB’ in the App/Play Store

Features:

• 8 analogue sensor inputs with the range 0..4V
• Outputs: 5V (pin 6), 3.3V (pin 7) and GND (pin 8) to power the sensors
• Can also be combined with up to 4x zone expanders
• Maximum of ONE analogue sensor board per OpenSprinkler 3/3.2
• 16 bit digital analogue to digital converter
• Compatible e.g. with the Truebner SMT50 or other analogue sensors
• Wide range of possible applications: Cistern fill level, temperatures or current humidity values
• New software with additional options, e.g.
  • Linear or digital irrigation adjustment based on soil moisture
  • Grouping of sensors with averaging
  • Permanent logging of sensor data
  • Integration of RS485 sensors via IP interface, e.g. for the Truebner SMT100 RS485 Modbus
  • Integration of analogue sensors that are connected to another OpenSprinkler
  • Additional API and extended GUI of the OpenSprinkler APP
  • Current value display on the APP start page, e.g. for cistern fill level, temperatures or current humidity values
  • Integration of current weather data
  • New: Monitoring and control
• Compatible with OpenSprinkler 3.2 AC/DC/Latch (not compatible with OSPi)
• Graphical display of logged sensor values:
  
• Support for the following sensors/types:
  • Truebner SMT100 RS485 Modbus (connected to RS485 adapter)
  • Truebner SMT100 Analogue version 3.3V
  • Truebner SMT50 Soil moisture and soil temperature
  • General measurement 0…4V
  • General measurement 0…3.3V i.e. 0…100%, e.g. fill level
  • Vegetronix VH400
  • Vegetronix THERM200
  • Vegetronix AquaPlumb
  • (Analogue) sensors of another OpenSprinkler, via network
  • Current weather data for data acquisition: temperature, humidity, rain, wind
  • Group formation: Several sensors can be grouped together, value formation from min/max/avg/sum
  • User defined sensor configuration
• Export of data as JSON or CSV (via API)
• All sensor data is pushed to a configured MQTT server.
