Grove - 6-Axis Accelerometer & Gyroscope
The Grove - 6-Axis Accelerometer & Gyroscope is a cost-effective Grove sensor integrated with a 3-axis digital accelerometer and a 3-axis digital gyroscope.
Overview
It has a low power consumption digital chip LSM6DS3 and power supply regulator which features high sensitivity and low noise interference. It can be configured to different levels of sensitivity to acceleration and can use different ranges of angular rate measurement. It is provided with a detailed SDK, which makes the prototyping process quick and easy.
This product is good for applications where tilt, motion, and tap sensing is needed.
Features:
- Grove interfaced and cost-effective.
- Digital-output for 6 DOF motion data.
- ±2/±4/±8/±16 g full scale leaner acceleration sensing range for various environment.
- ±125, ±245, ±500, ±1000, ±2000 degree per seconds(dps) for angular rate measurement range makes it versatile.
- A Detailed SDK for easy programming.
- Regulated power supply for reliable data to be collected.
- Programmed interrupts for different event.

Robot using Arduino Nano 33 BLE Camera Shield.
A lot of newer cars have a really nifty feature called “proximity unlock,” which automatically unlocks the doors when the driver approaches while carrying their key fob. When paired with a push-to-start ignition switch, the driver never has to take their keys out of their pocket. But Nick’s 2004 Subaru STI is too old to have come with that feature from the factory, so he used a couple of Arduino boards to create a DIY proximity unlock system. Car manufacturers need to pay serious attention to security when designing their access and ignition systems, but Nick had a bit more freedom. It is unlikely that any thieves would suspect his car of possessing a feature like this and so they wouldn’t even bother trying to hack it. Nick’s proximity unlock works by evaluating the received signal strength indicator (RSSI) of Bluetooth® Low Energy connection. If all else is equal, RSSI is inversely proportional to distance and that makes it useful for rough proximity detection. An Arduino Nano 33 BLE inside the car unlocks the doors when it has an active BLE connection with an RSSI over a set threshold. It unlocks the doors by shorting the switch with a 12V relay and it receives power from the car’s 12V system through a buck converter. The driver-carried device (equivalent to a key fob) can be either another Nano 33 BLE or Nick’s smartphone. In fact, it can be any device with a BLE adapter, so long as it can connect to the in-car Arduino with the proper device name. Now, Nick can enjoy his classic car and the convenience of proximity unlock.
