  • Industrial, rugged IP67-Certified enclosure with pressure vent
  • Replaceable large-capacity battery for restriction-free deployments
  • High-gain internal antenna with IPEX locking connector
  • Built with our expertise in manufacturing Bluetooth modules and sensors with superior RF performance and range
  • Industrial Temp. Range (-40º to +85º C)
  • Comprehensive Certifications for FCC, ISED, EU, UKCA, AS/NZS, RCM & MIC + Bluetooth SIG
  • Advanced deployment tools including mobile app (Android and iOS), sensor to cloud ecosystem, and engineering services.
  • Industry-leading support and product development teams: our engineers help customize and deploy your design.

The BT610 supports a wide range of interface options as a standalone product or can be coupled with off the shelf sensors for a variety of pre-canned applications, such as HVAC monitoring, three-phase AC current sensing, and tank monitoring solutions. These configurations enable users to read and report sensor data to the cloud, define alarm conditions, and configure the sensors through an associated mobile app (Android and iOS).

Use Our Tools to Estimate Battery Life and Calculate Thermistor Coefficients

How long will the battery last with your configuration? How do you determine the coefficients for thermistors purchased elsewhere? Use our calculators to estimate and generate the data for BT610 in your real-world applications.
