HW-044 Datasheet — Deep Technical Essay
The HW-044 is not a standardized component like a 555 timer or a MOSFET. It is a breakout module assembled from generic parts. Therefore, no single company publishes an “official” datasheet under the name HW-044. Instead, the information is derived from:
- Operating temp: −40 to +85 °C.
- Storage temp: −55 to +125 °C.
- Shock: 1000 g, 0.5 ms half-sine (sensor-dependent — MEMS may be less tolerant).
- Vibration: 20 g, 10–2000 Hz (application dependent).
- MTBF: design target >100,000 hours at 25 °C.
- Conformal coating: recommended in high-humidity or corrosive environments; note potential sensitivity change — recalibration recommended.
- Provide correct LV and HV voltages.
- Connect GNDs together.
- Do not exceed voltage ratings.
- Use short signal wires for best performance.
