SPECIFICATIONS Specified Assignment Content Design and make a circuit to that measures the pulse in your finger demonstrating the output on an oscilloscope, using Proteus software. PCB Design · The device shall be constructed on a single-sided printed-circuit board (PCB.) · The PCB must include your name, student number, and UCLan email. · If additional connections are required these shall be provided by 0Q links/wires. · The dimensions of the PCB should be no greater than 70 mm x 70 mm. Circuit Design Create a simple pulse sensor using photoplethysmography, it starts with a very low voltage signal so needs to be amplified and high frequencies and noise needs to be removed. Components o TCRT1000 Op amp LM358 Resistors and Capacitors of various sizes Voltage regulator LM7805 (if required) Power supply voltage range Regulate the power source so a safe DC value of 5 Volts is provided to the op amp circuit. Practical Work Construction Manufacture your given PCB, you will need to compare the design to your own circuit to calculate the correct format of the components. INSTRUCTIONS Tasks (keep a record in a log book though out, this is for your benefit is not required for marking) · Task 1. Research circuits and complete calculations. · Task 2. Design a circuit to meet the specification using Proteus · Task 3. Design a PCB layout for your circuit using ECAD Proteus, · Task 4. Interim Review at deadline. · Task 5. Manufacture your given PCB · Task 6 Test circuit in the laboratory, making appropriate measurements on an oscilloscope and then compare to the schematic simulation. · Task 7 Fault find circuit Power supply voltage range Regulate the power source so a safe DC value of 5 Volts is provided to the op amp circuit.

Proteus. Task 3. Design a PCB layout for your circuit using ECAD Proteus. Task 4. Interim Review at deadline. Task 5. Manufacture your given PCB. Task 6. Test circuit in the laboratory, making appropriate measurements on an oscilloscope and then compare to the schematic simulation. Task 7. Fault find circuit. Task 8. Analyse circuit, compare your results to the specifications, simulations, explain and include improvements. Please refer to the Marking Scheme Breakdown for more details regarding assessment and tasks ._ Pulse Sensor Heart Rate Monitor TASK 1 Research TCRT1000 Note the TRCT1000 does not exist on Proteus so we will be using a low voltage AC signal to simulate the circuit. Passive high pass filter Op Amp LM358 Non inverting amplifier Active low pass filter Buffer Voltage Regulator LM7805 to control the supply voltage. Pulse Sensor Heart Rate Monitor Task 2. Design and simulate a circuit to meet the specification using Proteus. Refer to the block diagram provided in this presentation. Task 3. Design a PCB layout for your circuit using ECAD Proteus.
