Dexcom One
The Dexcom Sensor is a continuous glucose monitoring (CGM) sensor used to measure glucose levels in real time throughout the day and night. It provides ongoing glucose readings without routine finger-prick testing, helping users better understand and manage their glucose trends. For use as part of a Dexcom CGM system. Always follow the manufacturer’s instructions. Each Sensor Lasts 10 days.
Note: Dexcom ONE+ is the newer version of Dexcom ONE. It features a smaller, all-in-one sensor with a faster start-up time and simpler application. Both systems provide continuous glucose monitoring with real-time readings when used with the Dexcom app.

The Dexcom Sensor is a wearable component of the Dexcom continuous glucose monitoring system, developed by Dexcom. The sensor is worn on the body and measures glucose levels in interstitial fluid, transmitting data wirelessly to a compatible receiver or smartphone app.
CGM systems provide real-time glucose readings, trend arrows, and alerts for high or low glucose levels. This can support improved day-to-day glucose awareness and assist with treatment decisions, when used as directed.
Sensors are designed to be worn continuously for a fixed period, depending on the specific Dexcom model. The sensor should be applied to recommended sites only and replaced according to the manufacturer’s guidance.
What is the Dexcom Sensor used for?
It is used to continuously monitor glucose levels in people who need regular glucose tracking, such as those with diabetes.
How does the Dexcom Sensor work?
The sensor sits just under the skin and measures glucose levels in interstitial fluid. Readings are sent automatically to a compatible device, providing near real-time glucose information.
Do I still need finger-prick tests?
Routine finger-prick testing is generally reduced, but may still be required in certain situations, such as when symptoms do not match readings or during sensor warm-up periods, depending on the model and clinical advice.
How does the Dexcom One+ compare to Dexcom One?
The Dexcom ONE+ system features a simple, one-touch sensor applicator with a 30-minute warm up. This means there is no separate transmitter. It’s also 60% smaller than Dexcom ONE, so it’s even more discreet and offers a 12-hour grace period before a sensor must be changed.
Where can the sensor be worn?
Approved wear sites vary by model and user age. Only apply the sensor to areas recommended in the manufacturer’s instructions.
Is the sensor waterproof?
Dexcom sensors are designed to be water-resistant for everyday activities such as showering. Always check the specific product guidance for limitations.
Can the sensor trigger alerts?
Yes. When paired with a compatible device, the system can provide alerts for high or low glucose levels, helping users respond promptly.
Is the Dexcom Sensor suitable for everyone?
Use should be based on individual clinical need. Always follow healthcare professional advice and the manufacturer’s instructions.
What should I do if the readings seem inaccurate?
If readings do not match how you feel, follow the troubleshooting guidance provided and check with a healthcare professional if needed.
