Help me to estimate the limitation of Raspberry Pi 3 B

I’ll build a circuit with
One BMP180 - Barometric Pressure, Temperature, Altitude Sensor,
One DS18B20 1-Wire Temperature Sensor - Waterproof,
One 5Volt Single Channel Relay Module.
Together these 3 components are considered as a set.
My question is how many sets can be successfully operated with a single Raspberry Pi 3 B Model?
