Need Longer Battery Life?
Monnit WIT2 Sensors provide the same features and benefits of our standard sensors but with the added value of AA batteries. The AA battery option is more robust at a wider temperature range and provides extremely long life for quicker heartbeats.
  • 2 replaceable AA 1.5V batteries.
  • At 1 hour heartbeat setting, included AA batteries will last more than 4 Years. **
  • Robust sensor housing.
