FAQ

Q: How do I choose between H3LIS100DLTR and H3LIS331DLTR?
A: The H3LIS100DLTR is the cost-optimized option for ±100 g applications. It provides 3.3× better sensitivity than the H3LIS331DL at ±400 g, at a lower unit cost. Choose the H3LIS331DLTR only if you need ±200 g or ±400 g ranges (military drones, high-speed impact testi

Q: What is the typical impact g-force in a drone crash?
A: Most hobbyist drone crashes (3″–7″ FPV quads) generate 20–80 g peak depending on speed, impact surface (grass vs concrete), and impact angle. Hard landings: 5–15 g. Mid-air collisions: 30–60 g. Full-speed into concrete: 80–150 g. The ±100 g range of t

Q: Can I use the H3LIS100DLTR on the same I²C bus as other sensors?
A: Yes. The SA0 pin selects between I²C addresses 0x18 (SA0=GND) and 0x19 (SA0=VDD). This allows two H3LIS100DLTR sensors, or one H3LIS100DLTR alongside other I²C sensors with different addresses, on the same bus without conflicts.

1. Product Overview

The H3LIS100DLTR is STMicroelectronics' ±100 g 3-axis MEMS high-g accelerometer — the fixed-range variant of the H3LIS331DL family optimized for applications where ±100 g provides sufficient headroom at a lower cost point. With 16-bit resolution providing 3.05 mg/LSB sensitivity, 32-level FIFO, dual programmable interrupts, and 10,000 g shock survivability, it delivers reliable impact detection, crash recording, and structural load monitoring for drone platforms where the extreme ±400 g range of the H3LIS331DL is unnecessary. The fixed ±100 g full scale simplifies firmware configuration while maintaining the same package footprint (TFLGA-16, 3×3 mm) as its multi-range sibling. The H3LIS100DLTR serves as the cost-optimized impact sensor for: (1)
