Frequently Asked Questions

What is the typical battery life for this sensor node?

With proper power management, ESP32-C3 based sensors can achieve 3-7 years on a CR2032 coin cell or 5-10 years on AA batteries, depending on wake-up frequency and data transmission requirements.

Calculate your duty cycle and power budget. BeiLuo FAE can help optimize for your specific requirements.

Does this solution support energy harvesting?

Yes, the ESP32-C3's ultra-low sleep current makes it ideal for energy harvesting applications. Solar, thermal, and vibration harvesting can all be integrated to extend or eliminate battery dependency.

Consider energy harvesting for outdoor or industrial applications with available ambient energy sources.

What is the typical BOM cost for the Battery-Powered Sensor Node?

The BOM cost varies based on configuration and volume. For the base configuration, expect $15-25 in 1K quantities. Volume pricing significantly reduces costs at 10K+ quantities. Contact BeiLuo sales for detailed quotation based on your specific requirements and annual volume forecasts.

Evaluate total cost of ownership including development time and certification costs.
