TLC551 IC Timer - CMOS 555 with 1V to 15V power, up to 1.8MHz
·
According to The Internet, 95% of electronic projects can be done with an op-amp or 555 timer chip. We're not so sure about it, but the 'triple nickel' (as we like to call it after we've had a gin&tonic) does come in handy for many simple analog or digital circuits. The classic part number is oft...

Gravity: Analog Infrared CO2 Sensor For Arduino (0~5000 ppm)
The concentration of carbon dioxide (0.03% usuallly) is related to daily life. Recently, there's a study showing that the atmospheric CO2 content has reached 0.0385% (385 ppm) which is the highest value since 2.1 million years. The raise of atmospheric CO2 content to some extent results in gl...
Gravity: Analog TDS Sensor/Meter for Arduino
The Gravity Analog TDS Sensor is an Arduino-compatible kit for measuring Total Dissolved Solids (TDS) in water. TDS indicates how many milligrams of soluble solids are dissolved per litre — the higher the value, the less clean the water. This sensor outputs a 0–2.3V analog signal that can be read...
Smart Grayscale Sensor
This time we reinvented the line-tracking sensor. Beyond recognizing two specific colors or output through digital or analog only, the Smart Gray Sensor has integrated both digital and analog output features. In digital mode, user can have two color data recorded through simple button operat...
