    Wireless Monitoring and Control System The wireless monitoring system enables a set of on/off switches to be monitored at a remote site via a wireless radio link and will replicate the state of the transmitter input switches on the receiver outputs. The remote switches could a float switch in a water tank, a door open switch on a door or gate, a motion sensor output, or a flow switch in a pipeline. Transmission range should be at least 500 ...

    Hi, I need a New device development. hardware and software. This is a pure integration solution of an existing devices. I would like to combine 4 signals (PPG, GSR, Temperature and Accelerometer) reading sensors. The device will contain a local memory, recharge battery and blue tooth interface to send real time data or saved data to a PC / Smartphone. This is a very simple project for an experts developers for this kind of devices, but it's impossible for inexperience ...

    Summary: Create a small, thin printed circuit board (PCB) that is a stopwatch that can share its time over bluetooth. Specificiations: The PCB will feature a microcontroller; several push-button single-poll, single-throw momentary switches; indicator LEDs; a bluetooth module; and a rechargeable battery. Ideally the entire assembly will be smaller than 40 mm long x 10 mm wide x 10 mm tall. Purpose: The device is essentially a bluetooth stopwatch. When the user pushes a button, the microcontroller should be able ...

    I need a circuit designed including a parts list and if possible the board solder design also. The circuit has to be as simple and as cheap to build as possible. The circuit will be used to detect a temperature change... So when the circuit is powered it will be at base level, if the temperature raises 3 degrees a red LED will light up. If the temperature rises back to base the LED will shut off. If the temperature ...
