March 2026 – Honeywell Extends Battery Life in New Wireless Sensor
Honeywell has announced the 5800PIR-10, a new wireless PIR motion sensor designed for its commercial and residential security systems. The sensor achieves an unprecedented 10-year battery life using a single 3V lithium battery, setting a new standard for the industry.
Key Specifications
- Battery Life: 10 years (typical use, 10 events/day)
- Battery Type: 3V lithium (CR123A), user-replaceable
- Detection Range: 15 meters (adjustable)
- Field of View: 90° (interchangeable lenses available)
- Wireless Protocol: Honeywell proprietary (345 MHz)
- Tamper Protection: Cover and wall tamper switches
- Pet Immunity: Up to 45kg (optional lens)
- Operating Temperature: -20°C to +60°C
- Dimensions: 120mm × 65mm × 45mm
Technology Behind the 10-Year Battery Life
Ultra-Low Power Components
The 5800PIR-10 uses the latest generation of low-power components:
- Panasonic EKMB PIR element: 1 µA standby current
- Texas Instruments MSP430: 0.5 µA sleep mode
- Custom RF transceiver: 4 mA transmit, 5 ms per event
- Efficient power management: Boost converter maintains voltage as battery drains
Intelligent Duty Cycling
The sensor uses a sophisticated wake-up strategy:
- PIR element always on (1 µA)
- MCU in deep sleep (0.5 µA) waiting for interrupt
- On motion, MCU wakes (5 µs), processes signal, and decides whether to transmit
- Signal processing on MCU (not transmitted) filters out false events before using radio
- Average current: ~1.8 µA
- Battery capacity: 1500 mAh (CR123A)
- 1500 mAh / 0.0018 mA ≈ 833,333 hours ≈ 95 years theoretical – but battery self-discharge limits to 10 years
Pet Immunity Features
The sensor offers multiple pet immunity options:
- Standard lens: Basic pet immunity up to 25kg
- Pet lens accessory: Up to 45kg with reduced sensitivity in lower zones
- Digital processing: Optional algorithm that analyzes signal patterns to distinguish pets
Installation Flexibility
Interchangeable lenses allow the sensor to be optimized for different mounting locations:
- Wide angle (90°): General purpose room coverage
- Long range (curtain): Hallways, up to 30m
- Pet immune: For homes with pets
- Ceiling mount (360°): For open areas
Integration with Honeywell Systems
The 5800PIR-10 is compatible with:
- Honeywell Lyric, Vista, and ProSeries control panels
- Resideo (formerly Honeywell Home) security systems
- Third-party systems via 5800 series receivers
Comparison with Previous Model
| Feature | 5800PIR (previous) | 5800PIR-10 (new) |
|---|---|---|
| Battery Life | 3-5 years | 10 years |
| Standby Current | 8 µA | 1.8 µA |
| Pet Immunity | Up to 25kg | Up to 45kg |
| Detection Range | 12m | 15m |
| Tamper Protection | Cover only | Cover + wall |
Pricing and Availability
The 5800PIR-10 is available now through Honeywell security dealers and distributors. List price is $79, with volume discounts for security installers. The sensor comes with a 5-year warranty.
Industry Impact
“Ten-year battery life is a game-changer for wireless security systems,” said a security industry analyst. “It means the sensor will likely outlast the customer’s contract. Installers can offer true ‘set and forget’ solutions with minimal maintenance calls.”
Future Developments
Honeywell hints at future sensors with:
- Energy harvesting for indefinite battery life
- Integrated camera for video verification
- AI-based pet/people discrimination
- Matter compatibility for broader ecosystem integration
