Magnetometer
Design efficient, low-power magnetometer sensors with reliable wireless solutions for precise orientation and mapping.
What is a Magnetometer?
A magnetometer measures magnetic fields and detects orientation relative to the Earth’s magnetic field. In IoT applications, magnetometers play a crucial role in navigation, asset tracking, and orientation sensing. Our solutions with magnetometers provide accurate magnetic field data to enhance situational awareness and precision across industries like transportation, manufacturing, and smart infrastructure.
Applications:
Magnetometer sensors are used in various industries to solve practical challenges:
Navigation Systems
Enhance accuracy in GPS navigation by providing heading information.
Asset Tracking
Detects movement and orientation changes for valuable equipment and goods.
Robotics
Enable precise movement and direction control for autonomous robots.
Smart Infrastructure
Monitor structural shifts by detecting changes in magnetic fields.
Consumer Electronics
Improve the accuracy of compass functions in smartphones and wearables.
The solutions with these sensors help businesses achieve better accuracy, security, and efficiency in their operations.
How Data Acquisition Happens
Magnetometers measure magnetic field strength along three axes (X, Y, Z). These analog signals are digitized by an embedded microcontroller and transmitted wirelessly via IoT protocols like LoRa, Bluetooth, or Wi-Fi.
The data is then sent to cloud platforms or edge devices, where it is analyzed for orientation, heading, or magnetic anomalies. Real-time dashboards and alerts ensure you are informed of critical changes, enabling fast and accurate decision-making.
Peripheral Integration
Magnetometers integrate smoothly with other IoT devices and systems, such as:
Gyro Sensors for comprehensive orientation tracking
Accelerometers for complete motion sensing
GPS Modules for advanced navigation solutions
This seamless integration supports holistic data collection, making your IoT ecosystem smarter and more responsive.

Usecases
We have used the Magnetometer in one of our Healthcare Product projects designed for the US Federal Prison to track and monitor the body vitals of prisoners in Custodies. Multiple sensors were integrated to the Handcuffs like Accelerometer, Heart Rates, Gyro, Magnetometer, Tampering History, etc.,.
The Magnetometer sensor helps us to precisely locate the prisoners’ position. A Flutter-based mobile application, integrated via Bluetooth, sends these real-time data to the prison monitoring officers for events like unusual motion or suspicious activity.
Project
Custody Protect
Wearable gadgets to monitor the Heart Rate, Accelerations, Magnetometer, Gyro of US prisoners under arrest were developed to prevent custody deaths.
