Client: Bao'an District, Shenzhen

Project Scope: PCB File Creation, BOM (Bill of Materials) List, PCB Schematic, PCB Design, Prototype Soldering, and Debugging

Project Highlights: Wired to Wireless Conversion

Doorbells, something everyone is familiar with – you press a button on the door or beside it, and it chimes inside, prompting the occupants to open the door. However, many times, these doorbells require wiring and frequent battery replacements, and their sound is monotonous. This gave rise to wireless doorbells.

Wireless doorbells, also known as remote control doorbells, are available in various types such as battery-free wireless doorbells, standard wireless doorbells, and visual wireless doorbells. They utilize consumer wireless technologies like Zigbee, WIFI, Bluetooth, 2.4G, etc., to create a new generation of doorbells.

The client provided us with a set of wired doorbells and had a simple request – to convert them into 2.4G wireless signal transmission, with a range of 400 meters, and the ability to play different melodies instead of the conventional chime. As we have extensive experience in wireless transmission and it is one of our core competencies, we took up the challenge with ease. However, proficiency doesn't imply complacency. We emphasize the importance of the process and minimizing errors, especially in the electronics industry where small details can lead to significant issues. Early on in the company's development, we encountered such detail-related problems that prolonged project debugging, resulting in potential customer loss. Thus, we cultivated a culture of meticulous attention to every detail, even for seemingly simple tasks, such as measuring a capacitor or resistor, where we would repeat the process numerous times (more than 20 times) with the same precision as the first attempt. This emphasis on details contributes to our high success rate and quick project debugging time. Some in the industry questioned our ability, wondering how we could achieve such fast project debugging. The truth is, behind our high success rate lies the dedication and attention to detail of our team, which has earned us wide acceptance from numerous clients.
