Clean Air, Smarter Power – PKNERGY Lithium Batteries for Air Quality Monitoring Devices

1. Power Requirements of Air Sensor Devices

Air quality sensors operate in distributed networks, either wall-mounted or portable, where continuous AC power is not always available.
They rely on rechargeable lithium batteries that deliver stable voltage for sensors, microcontrollers, and wireless communication modules such as Wi-Fi, LoRa, or BLE.

Traditional NiMH or alkaline batteries cannot provide consistent runtime or stability under variable loads.
In contrast, lithium-ion batteries offer higher energy density, longer service life, and excellent low-self-discharge performance—ideal for modern air monitoring devices.

2. PKNERGY Battery Configuration for Air Sensors

PKNERGY develops custom lithium battery packs optimized for compact air quality monitors and IoT environmental sensing equipment.

Typical configurations include:

• Voltage: 3.7V single cell or 7.4V dual-cell packs
• Capacity Range: 1500–6000mAh
• Discharge Current: 0.2C–1C continuous for stable sensor readings
• Cycle Life: >1000 cycles @ 80% DOD
• Built-in PCM/BMS for overcharge, short-circuit, and thermal protection
• Connectors: JST / FPC / Customized harness (OEM)

PKNERGY also offers smart battery modules with communication functions, providing real-time battery health, capacity and cycle information for predictive maintenance.
