Renesas Electronics Corporation, a supplier of advanced semiconductor solutions, has announced a strategic partnership with Tata Motors Ltd. (TML) and Tejas Networks Ltd., Tata Group companies, on the design, development, and manufacturing of Renesas’ semiconductor solutions for enhancing innovation across electronics systems for the Indian and emerging markets. “We see great potential in collaborating with…
Contactless temperature-measurement guns became popular during the Covid pandemic. Several places used this device to ensure safety protocols. However, one of the drawbacks of the contactless temperature measurement guns available today is that they measure body temperature — not the distance of the body (object) from the sensor. The body’s distance from the sensor is…
Timers are one of the common hardware features in all microcontrollers. Timers and timer interrupts are of great use in microcontroller applications. The timer interrupts are often used when precise timing is required without a fraction of error. All MicroPython ports have one or more timers. Some of these timers may be reserved for specific…

Amphenol / SSI Technologies P51 Pressure MediaSensors™ are micro-machined, absolute, sealed and gage pressure sensors for harsh and benign media with superior accuracy. The series comes in a choice of three pressure sensing type conventions: absolute, vented gauge, or sealed gauge. The compact and robust sensors, with a wide variety of fittings, measure pressures from…
Low power design is a system using a collection of techniques and methodologies for the purpose of optimizing battery life and reducing the overall power dissipation of the system. To optimize the power there are many low power techniques that depend on the level of the design selected, ranging from semiconductor technology to the higher…
8255 is general purpose programmable peripheral interface. It is used with many microprocessors and microcontrollers for various purposes. The device has three 8-bit ports port A, port B and port C. These ports can be used as input or output. These ports are further divided in to two groups A and B. Each group further…
The proposed simple electronic spy Bug circuit is basically a high gain amplifier using the IC 741 as the heart of the circuit and also a couple of high gain output transistors. The IC 741 if configured as a non-inverting amplifier which performs the function of a pre-amplifier stage. The gain of this IC 741 preamplifier stage may be varied as desired, using the pot across its input and output pin outs. The gain setting is used to set the sensitivity of the amplifier and is set to maximum so that even low volume speech conversation may be picked through it. The mic at the input transforms sound vibrations into minute electrical pulses, which is further amplified by the IC 741 to suitable levels before applying it to the output amplifier stage consisting of a standard DARLINGTON stage. This Darlington stage is made using a couple of high gain transistors bc107A’s.
