Sensor

general breakdown of the sensor categories they carry:

Environmental & Chemical

• Temperature & Humidity: Standard DHT-style modules, industrial thermocouples, and precision thermistors.

• Air & Gas: MQ-series gas sensors for detecting everything from methane to carbon monoxide, plus general air quality monitors.

• Liquid & Water Quality: pH sensors, TDS (Total Dissolved Solids) meters, and various liquid level and float sensors.

Motion, Distance & Proximity

• Distance/Ranging: Ultrasonic sensors, IR (infrared) obstacle avoidance, and specialized LiDAR or radar modules.

• Movement & Orientation: PIR motion sensors, accelerometers, and gyroscopes for stabilization and orientation tracking.

• Navigation: Line tracking arrays and GPS/GNSS modules.

Physical Force & Mechanical

• Pressure & Force: Flex/force sensors, load cells, strain gauges, and industrial-grade barometric pressure sensors.

• Vibration & Touch: Piezoelectric vibration modules, bump switches, and capacitive touch interfaces.

Electrical & Magnetic

• Power Monitoring: Current and voltage sensors (both AC and DC) for battery management or power consumption tracking.

• Magnetic: Hall Effect sensors, frequently used for calculating motor RPM or acting as non-contact limit switches.

Specialized & Biometric

• Human Interface: Fingerprint/biometric scanners and ECG/heart-rate monitors.

• Identification & Audio: RFID/NFC readers, sound detection modules, and raw imaging/camera sensors.
