Find if any living object (dog, cat, anyone) is in-front of my door (4-5 meter radius) even in the dark night. I am just interested in the presence of any living object. I will be checking inputs once every 5 seconds.
Good camera to capture image in day time (4-5 meter range from door) - I set up the OV7670 but the image quality is not good enough.
I am planning to use ESP32 and Arduino Uno (ATMEGA328P) for wifi to transfer images to my PC and then all heavy image computation/processing will happen on the PC.
I looked for options online, but most of them suggest Raspberry PI, and related camera and IR module which are costly. I am not able to convince myself for Pi as all image processing will happen on the PC.
Please suggest to Uno compatible
Cheap but good resolution camera for day time - range 4-5 meters, 90 -180 degree, image will be taken once every five seconds
IR module for night time process to find living objects in 4-5 meter range - image will be taken once every five seconds.
The Pi is a very common choice for taking pictures from high altitude balloons, if there was a better and 'low budget' Arduino option, one wonders why that is not used instead.
I am planning to use my existing AWS EC2 t4 once prototype is complete on PC (which just costed me $50 for 3 years and I using already it for one another purpose). PC will take rest after development
thanks Krishna. Ultrasonic sensor is new to me. I was looking IR so far. With 10 minute googling, I can find that HC-SR04 is cheap and has 400 cm range (just bordor) and US-100 Ultrasonic Sensor has 450 cm. I will check for US-100.
So why does this need to be 'low budget', whatever that means ?
For most all hobby projects it makes a lot of sense to stick to known proven stuff that works, such as the Pi. The small extra cost here in not an issue for a one off project.
Hi, is there any cheaper way for thermal imaging/camera for night time. MLX90614ESF Infrared IR Temperature Sensor Module is just ~$10, but it will just give temperature of near object than complete thermal image. MLX90640 IR Array Thermal Imaging Camera (~$90) and AMG8833 IR 8x8 Thermal Imager (~ $40) are costly. I am looking for something around $10-$15.
