Low Battery Detection System

I need a small pcb board powered by 9V battery that is connected with the board through a JST-ph 2.0 mm 2 pin connector The board has one 9V+ and 9V- output and 9V Input 1 en 2 with a JST-ph 2.0 mm 4-pin connector that will be connected with a healthcare sensor. The board has one 9V relays that will be active when input 1 is active, the relay has a NO/NC/9V- output with a JST-ph 2.0 mm 3-pin connector called "Fall" The board has one 9V relays that will be active when input 2 is active, the relay has a NO/NC/9V- output with a JST-ph 2.0 mm 3-pin connector called "Move" The third relay is for low battery detection of the 9V input. The system should trigger when the battery voltage drops to 6V or 10% of the full capacity. The relay have a NO/NC/9V- output with a JST-ph 2.0 mm 3-pin connector called BATT LOW Maybe use a 3V battery for this function to make shure this will always work. All relay have a SMD LED on the pcb board to see if they are active. When BATT LOW is active a seperate LED will be connected to the board with a 2 pin JST -ph 2.00 mm connector, this LED will be mounted in the cover When input 2 is active, a green led will be active a selected time period, 3, 5 or 10 min. The LED will be connected to the board with a 2 pin JST -ph 2.00 mm connector. this LED will be mounted in the cover Key Requirements: - Detect low battery at 6V or 10% - 3 Output relay with mechanical contact to connect to another system - LED on every relay - Design pcb as small as possible - Do not use programmable IC - The system should work completely analog - The design must be complete to take in production, deliver also the schematic, pcb board design and needed Berber file for production. Ideal Skills and Experience: - Experience with voltage detection circuits - Knowledge of relay integration - Background in healthcare-related electronic systems is a plus
