ACS712 Current Sensor Read

The ACS712 sensor read the current value and convert it into a relevant voltage value, The value that links the two measurements is sensitivity (you can find it on the datasheet) which – for 5A model – has a typical value of 185mV/A. The sensor can measure positive and negative currents (range -5A…5A), and power supply is 5V for the sensor, […]

Photocells Tutorial

1. Priciple Photocells are sensors that allow you to detect light. They are small, inexpensive, low-power, easy to use and don’t wear out. For that reason they often appear in toys, gadgets and appliances. They are often referred to as CdS cells (they are made of Cadmium-Sulfide), light-dependent resistors (LDR), and photoresistors.

Use NTC 10D-9 Thermal Sensor

We have a lot of NTC 10D-9 sensors and another similar sensors in stock, now we have a simple tutorial about how to use this one. You can get the NTC serials sensor here. First according to the datasheet, temperature and resistance is a function of the relationship. Rt = R *EXP(B*(1/T1-1/T2)) Of the above formula is […]
