Met with Kailun and her team of A level Chem officers (Stephanie, Andy, etc.) to discuss about developing a voltage sensor for electrochemical measurements. Will simplify and miniaturize the setup for easy student use, as well as development a basic handout. Also shared about my experience in using Arduino microcontrollers with my SIA students to do group projects.

Arduino UNO R3 --> MQ135 Sensor

//Coded and Tested By: //Sheekar Banerjee, AI-ML, IOT Solution Engineer and Researcher void setup() { // initialize serial communication at 9600 bits per second: Serial.begin(9600); } void loop() { int sensorValue = analogRead(A0); // read the input on analog pin 0: Serial.println("The amount of CO2 (in PPM): "); Serial.println(sensorValue); delay(2000); }
Necessary Information:
Normal air returns approximately 100-150 ppm

Alcohol returns approximately 700 ppm

Lighter gas returns approximately 750 ppm

It took almost 40 minutes for my sensor to preheat. it may take more or less in different situations. On the serial monitor, you can see the values of the analog pin being detected. Currently, in my case, they are around about 100 ppm which indicates normal air. But when breath out right in front of sensor, suddenly the reading rises up closing to 170-220 PPM.

PPM stands for "Parts per million"

Aceton (C3H6O) Measurement:

Arduino UNO R3 --> MQ135 Sensor

//Coded and Tested By: //Sheekar Banerjee, AI-ML-IOT Solution Engineer and Researcher int R0 = 176; int R2 = 1000; float RS; float PPM_acetone; void setup() { Serial.begin(9600); } void loop() { int sensorValue = analogRead(A0); // read the input on analog pin 0: // convert to voltage: float volts = sensorValue * 5; volts = volts / 1023; // calculate RS RS = R2 * (1-volts); RS = RS/volts; // calculate acetone PPM PPM_acetone = 159.6 - 133.33*(RS/R0); // print out the acetone concentration: Serial.println(PPM_acetone); delay(3000); // delay in between reads for stability }

I shared on the use of Arduino microcontrollers in the teaching and learning of Science and Physics. The CPDD colleagues discussed many interesting ideas to support development in schools and staff training. Dr Darren Wong also suggested submitting the idea for Innergy Award in future.

There are 5 themes for STEM ALP in schools. Timothy suggested that I join STEMP ALP OPAL for additional STEM resources shared by schools. He is interested in the issues on promoting women representation in STEM.

1. Most happy to meet ex-colleagues mine and those of my colleagues and ex-student :-)
2. Appreciate the sharing by electronics and computing teams arranged by Fang Fang. These provided good overall knowledge of the curriculum plans, resources and instructional practices that are happening in the schools at all levels supporting the STEM directions of MOE.
3. There are many opportunities for collaboration and the development of specific ideas for
(a) early introduction of technology (microcontrollers MCUs) in lower secondary, to support upper level curriculum and/or research projects
(b) infusion of MCU-based and non-MCU (just breadboard circuits/components) lesson plans in Physics curriculum
(c) enhancing digital literacy of how STEM plays a critical part in our daily life (smart technology, devices, robotics)
