Sensore di movimento PIR Panasonic EKMB1300100K tensione di esercizio 2,3–4 V

Panasonic EKMB1300100K is a passive infrared (PIR) motion sensor engineered to detect human movement with low power consumption. Specified to operate within a 2.3–4 V supply range, this sensor is suitable for battery-powered and low-voltage DC electronics. The compact module integrates a stable PIR sensing element and standard output behavior for straightforward connection to microcontrollers, lighting controls, and alarm systems.

Advantages

The sensor provides reliable detection of human motion with minimal current draw, making it appropriate for energy-conscious applications. Its wide operating voltage range allows flexible integration into systems that use single-cell lithium batteries, coin cells with boost converters, or common low-voltage DC supplies. The compact form factor and industry-standard signal output simplify installation in confined enclosures and retrofit projects.

Suitable for

• Occupancy detection in rooms, corridors and small offices
• Automated lighting control and energy-saving systems
• Battery-powered alarm and security devices
• Embedded projects with microcontrollers (IoT nodes, smart sensors)

Key specifications

• Detection type: Passive infrared (PIR) for human motion
• Operating voltage: 2.3–4 V DC
• Power consumption: optimized for low-current operation (typical values depend on operating conditions)
• Signal output: standard digital output compatible with TTL/CMOS logic levels within the specified supply range
• Typical mounting: panel or enclosure mounting with small footprint
• Environmental suitability: intended for indoor use in standard temperature ranges (refer to manufacturer data for exact limits)

How to use

Connect the sensor to a suitable 2.3–4 V DC supply and reference ground, then route the digital output to an input pin of a microcontroller or to a logic-level interface on your control board. Allow a short warm-up time after power-up for stable PIR operation. Implement basic signal filtering and debounce logic in firmware or hardware if the target application requires stable event detection in environments with intermittent thermal disturbances. When using battery power, configure sleep or wake sequences in the system to extend operational life while accounting for the sensor's detection and stabilization times.

Recommendations

Place the sensor where it has an unobstructed view of the monitored area and avoid aiming it directly at HVAC outlets, windows with direct sunlight, or heat sources to reduce false triggers. For reliable performance in embedded designs use the recommended supply voltage within the 2.3–4 V range and follow grounding and decoupling practices. Consult the manufacturer's technical datasheet for precise timing, sensitivity adjustments, and environmental limits prior to final integration.
