Hitachi H48C 3-Axis Accelerometer Module

Hitachi  H48C 3-Axis Accelerometer Module

General Description

The Hitachi H48C 3-Axis Accelerometer is an integrated module that can sense gravitational (g) force of ±3g on three axes (X, Y, and Z). The module contains an onboard regulator to provide 3.3-volt power to the H48C, analog signal conditioning, and an MCP3204 (four channel, 12-bit) analog-to-digital converter to read the H48C voltage outputs. All components are mounted on a breadboard-friendly, 0.7 by 0.8 inch module. Acquiring measurements from the module is simplified through a synchronous serial interface. With the BASIC Stamp® 2 series, for example, this is easily handled with the SHIFTOUT and SHIFTIN


• Measure ±3 g on any axis
• Uses MEMS (Micro Electro-Mechanical System) technology, with compensation for calibration-free operation
• Onboard regulator and high-resolution ADC for simple connection to microcontroller host - compatible with BASIC Stamp 2 series SHIFTOUT and SHIFTIN commands
• Free-fall output indicates simultaneous 0g an all axes
• Small, breadboard-friendly package: 0.7" x 0.8" (17.8 mm x 20.3 mm)
• Wide operational range: -25° to 75° C

Application Ideas

• Tilt measurement in robotics applications
• Multi-axis vibration measurement in transit and shipping systems
• Multi-axis movement/lack-of-movement for alarm systems
