New Firmware and Manual for the WMS Mk2

Just before the summer vacations I finalized the Wireless Multi-sensor Mk2 firmware that I have been working with for quite some time.

News,

  • CO2 sensor S8 from SenseAir is now supported. It can be connected to the Event Input after changing the input mode of the Event Input (c.f. Manual). You can get the CO2-sensor here.
  • MAX31850K support. This chip is a Thermocouple Type K to 1-wire chip. This makes it possible to make a Type K thermocouple wireless. It can output 409.6°C as the highest temperature. It is a limitation set by the protocol I use. Here you can find a MAX31850K-module, m.nu.
  • DS2450 support. This is a 4 channel AD converter. All 1-wire sensors based on this chip will be compatible with the WMS Mk2. This,  this, this, this and this is also compatible modules since they are based on the DS2450 chip.

Improvements,

  • Events are now sent as a LMST-606 device. An ON or OFF signal will be sent depending on if the input pin is pulled up or pulled down.
  • The Manual is out in a first revision.

All Wireless Multi-sensors Mk2 will be shipped with this new firmware from now on.
