I am recently doing a project of Iris recognition system for biometric personal identification. I have tried so many journals/ papers to understand how iris recognition works. But did not implement a matlab program. everywhere i found some instructions but couldn't implement it successfully...
@Mithun_K_Das , I was also doing a project PIC16F877A with 8MHz external X-Ta and temp sensor is DS18B20. In simulation it only shows the temp like 31.0,32.0,33.0 . but in real (breadboard) it shows fractional value like 31.4,32.6 ect. did you try in real hardware?
1. GH-312 sensor which contains MQ-2 sensor (It has 3 pin = +, OUT, - )
2. SEN-1327 LPG Gas Sensor Module which contains MQ-6 sensor
(It has 4 pin= OUT, ANG, 5V, GND )
I do not find any datasheet for these gas sensor module. or MQ-2 and MQ-6 sensor. Would anyone please help me to find...
I want to modify the above circuit and program.
When the (temp<=20 ), the PORTD.RD0 and PORTD.RD1 should be power ON. And connecting this port with ULN2003A (1C & 2C) , i want to drive two relays(RL1 , RL2) to drive a Heater ON (In the schematic)
Again when the (temp>=30), the PORTD.RD2 and...
I am using Micro C Pro and Proteus for simulation. Here is The Program of Temperature Sensor (DS18B20 + PIC16F877A)
It woks almost right but does not show the negative (-) sign before the negative Temp. where is the problem? Can anyone please help me to modify the code
here is my...
