TouchNot Pro smart tag equipped with multiple sensors and an ear-splitting alarm offers a subscription-free cloud service

The latest crowdfunded device, known as the ‘TouchNot Pro’, is a smart tag designed to keep personal possessions safe and prevent theft from happening in the first place. It has both touch and motion sensors onboard to monitor the item and the area around it. Beyond that, the TouchNot Pro smart tag offers some useful features to maintain user privacy alongside safeguarding personal belongings. Therefore, if any sort of suspicious activity occurs, it gets triggered and sounds an ear-splitting alarm that is enough to make anyone  alert and get notified about the possible chances of theft.

The TouchNot Pro smart tag is equipped with an ESP32-S3-MINI-1 microcontroller that is powered by a 500 mAh LiPo battery that can last months on standby (as long as the alarm is not being triggered often). To maintain user privacy, the smart tag uses a suite of sensors instead of cameras. Sensing is performed by an Analog Devices ADXL345 touch/vibration sensor and a Texas Instruments VL53l0x time-of-flight motion sensor. This combination enables the device to recognize both physical contact and nearby activity. The device also sends a notification via a subscription-free cloud service to alert the owner without any additional fees.
