Digital Accelerometer PWM Output

Memsic (http://www.memsic.com) provides the 2020 in a surface-mount format. Robosoft Systems mounts the circuit on a through-hole providing all I/O connections so it can easily be inserted on a breadboard or through-hole prototype area.

Features:

• Measures ±3 g on each axis
• Simple pulse output of g-force for each axis
• Convenient 6-pin 0.1" spacing DIP module
• Low current at 3.3 or 5 V operation: less than 4 mA at 5 VDC

Sample Applications:

• Dual-axis tilt sensing for autonomous robotics applications
• Single-axis rotational position sensing
• Movement/Lack-of-movement sensing for alarm systems
• R/C hobby projects such as autopilots

Key Specifications:

• Power requirements: +3.3 to +5 VDC
• Communication: TTL/CMOS compatible 100 Hz PWM output signal with duty cycle proportional to acceleration
• Dimensions: 0.42 x 0.42 x 0.45 in (10.7 x 10.7 x 11.8 mm)
• Operating temp range: 32 to +158 °F (0 to +70 °C)
