Bluetooth Sensor Tags

Battery Free Bluetooth low energy sensor family

Wireless and battery free sensor data with standard Bluetooth Low Energy.

The BLE sensor family works with external sensors, meaning the items below are just examples of what our technology can do for you. Should any of our evaluation boards spark your interest but you need a different sensor or magnitude to be measured, our team is ready to assist you in creating custom solutions based on this technology. We understand that your business may have unique needs, and we’re here to tailor these products to meet your specific requirements.

The Rise of Zero‑Maintenance Sensors: A Game Changer for Industry
Zero‑maintenance sensing is transforming industrial IoT—but it isn’t a single technology. It’s a strategy built around choosing the right architecture for the environment: battery‑free when a reader can reach the sensor, battery‑powered when autonomous updates are needed, and wired when continuous real‑time data is essential. With battery‑free sensing now scaling rapidly—from USD 73.2M in 2025 to a projected USD 512.8M by 2035—industries are adopting long‑life, low‑touch monitoring across data centers, logistics, and civil infrastructure. The real shift isn’t eliminating batteries everywhere; it’s eliminating unnecessary maintenance while keeping sensing reliable, sustainable, and scalable.
