- T.K. Hareendran.. biased by IC1 ( LM555 ). Here IC1 is wired as a medium current inverting line driver, switched by an encapsulated light detector (10mm LDR). Multi-turn trimpot P1 sets the detection sensitivity. When ambient light dims, transistor T1 ...Oct 12, 2010
- .. ultrasonic range finder ! This quick dirty PIC ultrasonic range finder will find a place in numerous projects : presence detector, robotics, car parking, distance measurement.. With a few cheap components and less than 200 bytes of ...Nov 2, 2010
- .. device is an integrated phase control circuit - Siemens TLE3103. It contains its own power supply, a zero voltage crossing detector circuit and a logic driver. An additional feature is the low voltage input to enable/disable triac firing ...Nov 8, 2010
- .. during the sensor off periods. In this example, a solar cell and a one-farad capacitor are used to power a remote motion-detector that uses an RF link to transmit the occurrence of any moment to a central monitor. This type of sensor ...Apr 29, 2019
- Nick Ierfino.. the comparator to avoid noise when determining an AC signal’s rising edge. A few adjustments to a zero-crossing detector allow it to operate above the noise level (see the figure). The transformer has very low power-driving ...Feb 16, 2011
- .. Although the mains lamp has quite high AC component, the sharp peaks generated when the ball blocks the light from the detector allow high accuracy event detection. The software displays the measured time and the number of detected ...Mar 7, 2012
- Metodi Iliev.. R 7 limit forward currents through the LEDs. For greater sensitivity, you can replace the LEDs with high-input-impedance ac-detector circuits. The circuit's final version includes indicators that show whether all three phases carry ...Apr 3, 2023
- .. Varkey Here is a system based on PIR motion detector module BS1600 (or BS1700) that can be used for security or corridor lighting in powersaving mode. The 12V ...Jul 12, 2011
- Steve Hageman.. simple peak detector in Figure 1 is the result of a need for a single-5V-supply, level/clipping indicator for a multimedia-PC ...Jul 29, 2021
- Tom Au-Yeung Wilson Tang.. temperature data. Comparator IC 4 connects to IC 3 ’s RSSI (received-signal-strength indicator) with an internal peak detector. The external RC follows the peak power of the received signal and compares it with a predetermined, ...Sep 13, 2012
