Wind speed range: 0–5 m/s (bidirectional)
Repeatability: ±3% FS
Response time: < 20 ms
Output signal: Analog voltage 0.2–3.3 VDC (non-linear)
Power supply: 5 VDC ±1%, working current < 10 mA, power consumption < 50 mW
Operating temperature: -10 ℃ ～ +70 ℃
Storage temperature: -20 ℃ ～ +80 ℃
Humidity: < 95% RH (no condensation, no freezing)
Maximum pressure: 50 kPa
Preheating time: 1 minute
Size / Packaging: Micro straight-through, approximately 25.4 × 23.0 × 7.3 mm; 3-pin 2.54 mm pitch
Features: Bidirectional measurement, anti-blockage structure, high sensitivity, capable of measuring very small wind speeds
II. Applications and Usage Scenarios
Equipment cooling air path monitoring (most commonly used)
Projectors, medical equipment, industrial cameras, industrial control computers: Monitoring cooling fan wind speed / air volume, filter blockage alarm, anti-overheating
HVAC ventilation and fresh air system
Small ducts, air outlet of air conditioners, fresh air equipment: Measuring wind speed, determining air pathness, feedback air volume
Air purifiers / purification equipment
Monitoring filter blockage, fan failure, intelligent reminder for filter replacement
Fan / fan status monitoring
Server fans, vehicle fans, small blowers: Real-time detection of abnormal wind speed, blockage, stoppage
Laboratories / small flow monitoring of instruments
Dry air, nitrogen, etc. low flow rate monitoring (non-explosion-proof, non-corrosive environment)
III. Comparison of FS7002 Series (Selection Reference)
FS7002-A: 0–2 m/s, ±4%FS → Low wind speed / High sensitivity
FS7002-B: 0–5 m/s, ±3% FS → General medium range (most commonly used)
FS7002-C: 0–10 m/s, ±2%FS → High wind speed / Large air volume
