ZigBee Temperature Measurement Module (CC2530 Core)
Both modules are based on TI CC2530 2.4GHz ZigBee SoC, designed for industrial and power temperature measurement. The main differences lie in power supply mode and application scenarios. They are classified and described below in terms of core definition, power supply, temperature measurement, networking, applications, advantages and disadvantages.
1. CC2530TR2.4-YY Active Sensor Module (ZigBee Temperature Measurement Solution)
1.1 Core Definition
ZigBee wireless temperature measurement terminal with active power supply, powered by external power (battery/DC). Integrated with temperature sensor and CC2530 RF unit to realize temperature acquisition and wireless reporting.
1.2 Power Supply
- External DC power supply (e.g. 3.7V lithium battery, 5V/12V DC)
- Support low-power sleep; battery life can last several months to 1 year (depending on sampling frequency)
1.3 Temperature Measurement Features
- Measuring range: -40℃～+125℃ (industrial grade), accuracy ±0.5℃
- Sensors: built-in NTC/PT100/DS18B20, support contact temperature measurement (busbar, switchgear contacts, etc.)
- Sampling period: configurable (1s～30min), support threshold alarm reporting
1.4 ZigBee Features
- Protocol: IEEE 802.15.4 / ZigBee PRO, 2.4GHz ISM band
- Network role: End Device, can join coordinator/router network
- Communication distance: 50～100m line of sight, 30～50m through walls
- Power consumption: μA level in sleep, mA level in operation
1.5 Typical Applications
- Temperature measurement for switchgear/ring main unit contacts, cable joints, busbars
- Battery-powered wireless temperature monitoring (no strong electricity environment)
- Wireless temperature monitoring for industrial equipment, HVAC, storage environment
1.6 Advantages & Disadvantages
- Advantages: flexible installation, no strong power required, low power consumption, suitable for no-power scenarios
- Disadvantages: need regular battery replacement/charging, not suitable for long-term maintenance-free scenarios
2. CC2530TR2.4-XS Passive CT Power Module (ZigBee Temperature Measurement Solution)
2.1 Core Definition
ZigBee temperature measurement terminal with passive CT power collection, which gets power from high-voltage/high-current lines through current transformer (CT). No external battery or power supply is needed, realizing integration of "self-power supply + temperature measurement + wireless transmission".
2.2 Power Supply
- CT power collection: obtain energy from AC lines (e.g. 10kV cable, busbar)
- Startup threshold: ≥5A line current, support wide current range adaptation
- Energy storage: built-in super capacitor/lithium battery, maintain short-time operation without current
2.3 Temperature Measurement Features
- Measuring range: -40℃～+150℃ (power industry), accuracy ±0.5℃
- Sensor: contact type (attached to cable/busbar surface), support high-voltage isolation
- Sampling: real-time/timed reporting, multi-level over-temperature alarm
2.4 ZigBee Features
- Protocol: same as YY version (2.4GHz ZigBee)
- Network role: End Device/Router (depending on power stability), support network relay
- Communication distance: same as YY version, suitable for complex electromagnetic environment in power cabinets
- Power consumption: unlimited endurance by CT power, long-term continuous operation
2.5 Typical Applications
- Temperature measurement for 10kV/35kV cable joints, switchgear contacts, transformer bushings
- Passive wireless temperature measurement for high-voltage busbars, GIS equipment, ring main units
- Power equipment monitoring in strong electricity scenarios where wiring/power supply is unavailable
2.6 Advantages & Disadvantages
- Advantages: passive maintenance-free, battery-free, suitable for high-voltage/strong electricity scenarios, long-term stable
- Disadvantages: rely on line current (no power collection without current), need CT coupling for installation, slightly higher cost
