Q: Does it have any contacts that can be used as a signal output to a controller?

Rii7 The battery leads are the only wires that are exposed.

Augustin When smoke is detected it will send a short RF signal in the 433mhz frequency. If you have a 433mhz RF receiver connected to your Arduino you can monitor and detect that "ping"... Mine is connected through a Sonoff RF to WiFi bridge for home automation

xradiomusicx la tensione massima supportata è 3.3v occorre un convertitore se si alimenta ad una tensione più elevata

VolkerP Howmuch is the minimum voltage drop between input and output at about 2.5A? I want to use it as a 12V (nominal) power supply from a lead battery (range 10-13.5V). So when input is 12V, what is the output?
Q: Necesita cargar con saldo dinero algún. Chip, tarjeta sim? O nada de eso?

VolkerP Si no dice nada de eso, no lo tiene. Además, hay que estar consciente de que bluetooth no llega a más que 10-15 m. No veo sentido de ponerlo a la mascota si esta no puede ser descubierta a más que 10 m de distancia. Puede funcionar para encontrar objetos que estan cerca a ti, pero no los encuentras.

VolkerP Canit be used instead of Arduino Nano in existing boards (is it pin by pin interchangeable)?
Q: The valve open only 0% and 100%, or can be adjust the flow?

VolkerP it's ON/OFF only

VolkerP You are correct I wanted to use them to work with a 5V relais off a 12V power supply but they use as much current from the 12 V as if this was a simple resistor instead of a switching regulator. they draw about 35mA on their own @12V DC, nearly half a Watt and get pretty hot without doing anything else. Crap
