...are based on each other . the pcb is a 33mm circle with 2 mounting screws. The pcb has 3 sensors on one side that need to be exposed on the front. The front of both cases will share the same cutout / vend holes like this: Looking for design where its a round top with main hole for Time of flight sensor with inset to help with shadow . Should go close to the sensor on the the board. Check sample image for how this cut out should be. On either side of the TOF sensor there is a LUX and temp sensor these also need opening but can be smaller . I want to hide these cut outs by having some vent holes that happen to go over these two sensors. PCB needs to be attacked to both cases, Preferably it just snaps into the case and is securely help in place and can not...

I ...portable low-cost open-source wireless spectrophotometer based on the development done by Katrina Laganovska. I want to use her Arduino code and install on an Arduino NANO 33 IOT board to support the transfer of the sensor data over wifi to an external MQTT broker. I have the hardware and require an experienced Arduino programmer to develop the relevent software changes. See Katrinas document on how to implement her solution. However I do not want a mobile app or a desktop app, I just need to take the sensor data from the arduio nano iot 33 board and transfer to an MQTT backend broker.

Need basic games structured to exploit the functions of the human body such as the legs and hands by making it move in all directions as to aid physical therapy of said body parts. The game should be customised as per the sensitivity and flexibility of the hand as well as the ankle. For example, in the game for hand rehabilitation, the hand position and function should be sensed using a sensor (leap motion) placed on top of the table and as the user carries out different tasks put forward to the them in the game, the users hand should be seen and replicated with great sensitivity to show real world movements of the hand. It should be able to assess the angle of bend of each finger as well as the hand joint. The game for ankle rehab should be carried out similarly but much more ef...

I have a project I need doing. It involves the following: 1) A RPi, 2) Waveshare Barcode scanner () 3) A 16x2 LCD screen 4) A weight sensor module () 5) An RFiD module I need help with making everything work first with the most basic code, so we have the circuit correct. I already have LCD and barcode scanner working (barcode scanner has UART data receiving issue, but we can discuss it later). I will then give a logic on how everything will work together and you will help write the code for it for me. As this is time sensitive, please do not bid if you 'can' work with RPi but don't normally do. I really need someone who is an expert on this please and has worked with sensors with different

I'm having a difficult time making work this sensor: I'm trying to read it with a rs485 to ttl converter and arduino nano but the sensor is not working fine. It works when reading just 1 of the 7 parameters but when using more it gives incorrect readings. I've been reading a lot in forums and it seems to be a pretty usual problem but could't solve it yet. I know is maybe too much specific and you'd need to have the sensor but I risk myself and post this job. Afterwards, I need that data to be transfered to Arduino MKR 1310 to make it connect to an already existing LoraWan connection.

Required system consists of a pressure sensor and a DC motor which will be able to connect to the Internet through WiFi connectivity and send the measured pressure values to a server. User will be able to observe the values through a web UI (dashboard). User should also be able to start and stop the motor which is connected to device in addition with the sensor. The system will measure the pressure continuously and start the pump automatically above a certain pressure value and stop the motor when the pressure gets below the preset value. User will be able to see all of the activity through the web dashboard.
