Issue

  • Battery trend down
  • Root cause for the battery downtrend: to be identified

Firmware version

Metadata: Location, dep_id

  • Russell Street
  • duly_pro_vervet

Fix

  • tbd

Sensor condition

  • physically in good condition
  • Solar panel operational
  • Heltec operational
  • Maxbotix good condition

Antenna condition

  • Broken antenna
  • But was transmitting data with good RSSI and SNR in indoor lab conditions

Power consumption analysis

  • Power consumption in all sensor states - Tx, Rx, and sleep seems normal

Here is a battery trend plot for a sensor in Hamilton Beach with the deployment_id duly_pro_vervet .

Screenshot 2023-03-22 at 12 18 28 PM

The battery was swapped on 3/17/23 but the trend still is the same. Need further investigation.

Speculation of possible causes:

  • Failed Panel
  • Battery health deteriorated
  • Damaged Solar Cable
  • Fried board/radio
  • High power consumption due to broken antenna

TBD: Loss of network detection algorithm is needed to prevent attempting transmission when an antenna is broken to prevent hardware damage.
