Basics

The battery has no reverse polarity protection. Double check the polarity marked on the battery holder and your battery before installing.

The button on the PCB, to the right of the USB socket, has two functions:

  • Reset (short single press)
  • Bootloader Mode (short double press)

The red LED is indicating an error. This could be a configuration issue or a hardware problem

The plugs are color-coded and must be plugged in accordingly. The pinout is labeled on the PCB

  • Solar cell 2-pin black
  • External battery 2-pin white (remains free when using the battery holder)
  • UART (WS80/WS85 ultrasonic sensor) 4-pin black
  • Davis 6410 red
  • I2C (for display) blue

The solder jumper (J1) connects the power of the USB port to the solar cell input (with a diode). When the jumper is closed (default) the battery can be charged by USB (65mA charge current). There currently is no battery indicator. The software is not designed to send weather data while USB is enumerated.

Setup recommendations

  • It is best to insert the battery into the mounting bracket before installation to avoid mechanical damage
  • The circuit board should be firmly screwed to the antenna. It can be turned together with the white, ribbed ring and should be turned so that the circuit board does not touch the housing (in case condensation forms there)
  • After connecting to USB, the reset button must be pressed once (reset)
  • The electronics box is mounted on the pole with the antenna facing downwards. This prevents water from running through the cable gland into the housing.
  • The solar cell should face south if possible. If the pole is blocking the line of sight of the antenna to the ground station/OGN receiver, a deviation of +-60° is possible without any problems.
  • The housing is designed to be positioned vertically to avoid snow deposits on the solar cell. Snow deposits on the solar cell of the WS80 sensor are not critical as it is also supplied with power by the electronics box.
  • The aluminum tube of the WS80 sensor should be horizontal or slightly inclined so that water runs out of the tube away from the sensor.
  • It is advisable to check the function before installation on the pole. The LED of the WS80 sensor flashes every 4 seconds. When sending weather data, the blue LED on the circuit board lights up briefly.
