Tuned Infrared (IR) Detector Circuit
The article is a continuation of the earlier post where we tried to find a solution for creating unique infrared IDs for trains in a model locomotive system. Here we […]
Simple Shadow Sensor Alarm Circuit
This shadow detector circuit operates using two LDRs and effectively detects the difference between the light levels and triggers a loud audible warning siren. In circuits which uses a single […]
Make this Insect Wing Signal Detector Circuit
The article discusses a VLF receiver circuit used for detecting insect wing beat signals, the idea was investigated and built by Mr. Steven Chiverton. Insect Wing Triggered ELF An incredibly […]
Non-Contact Current Sensor Circuit Using Hall-Effect IC
In this article we learn about a simple non-contact current sensor circuit using a hall effect sensor IC. Why Hall Effect Sensor When it comes to sensing current (Amps) linear […]
Linear Hall-Effect Sensor – Working and Application Circuit
Linear Hall-effect ICs are magnetic sensor devices designed to respond to magnetic fields to produce a proportionate amount of electrical output. It thus becomes useful for measuring the strength of […]
