TI Temp Sensor vs Thermistor

10

Why a TI IC Temp Sensor

Simplicity:

• No additional circuitry required

• Better PSRR & Noise Immunity

• Easier to layout

• No curve fitting or lookup table

• Eliminate polling for over / under temp detection

Wide range of interfaces

• Analog, I2C, SPI, 1-wire, UART, Pulse Counter

• Cabled interfaces (coming 2015)

35oC

Thermistor IC Sensor

Accuracy:

• Accuracy is guaranteed (zero calibration needed)

• Analog outputs are linear

• Little to no self heating

Power

• Digital Interface options down to 4.8uW

• Built-in low power modes

• Programmable wake->sample->sleep>repeat mode

• High-resolution integrated temperature sensor

• Smallest size solution

An Introduction to Humidity

• What’s RELATIVE HUMIDITY? – Ratio (at a fixed temperature) between actual water vapor and saturation water vapor expressed as percentage (saturation is the max

water vapor)

%𝑅𝐻 =𝐴𝑐𝑡𝑢𝑎𝑙 𝑊𝑎𝑡𝑒𝑟 𝑉𝑎𝑝𝑜𝑟

𝑆𝑎𝑡𝑢𝑟𝑎𝑡𝑖𝑜𝑛 𝑊𝑎𝑡𝑒𝑟 𝑉𝑎𝑝𝑜𝑟 𝑓𝑖𝑥𝑒𝑑 𝑡𝑒𝑚𝑝𝑒𝑟𝑎𝑡𝑢𝑟𝑒

Saturation water vapor start to condense

– %RH change significantly with the temperature • +1°C variation -4%RH relative humidity • Precise temperature measurement is needed

• Dew Point - Temperature at which moisture condenses (air is saturated) – to identify this temperature a precise temperature sensor is needed.

– Avoiding the condensation is important is several application as automatic windshield defog, industrial process etc.

– Combination of accurate humidity and temperature sensor is needed

HDC100x/HDC3000 intrinsic dust resistant

• Dust falls on top of the sensing element reducing the performances until the complete blockage of the sensor

• Some competitors suggest to cover the sensor with a filter/grid (very expensive more than the device itself)

• HDC100x/HDC3000 has the sensing element on the bottom part of the sensor.

• Sensing element is intrinsically protect from the dust that falls on the top part

DRV425 – How it works

45

High precision fluxgate

magnetic sensor detects

the magnetic field vector in

its axis.

Signal is amplified and used to

drive a compensating current

that keeps the sensor operating

with 0 field.

The current driving the

compensation coil is proportional

to the magnetic field to be

measured with a very stable gain

factor.

The shunt resistor

converts the current into

voltage and sets the

amplification factor.

The shunt sense amplifier

(G=4) provides an output

proportional to the

magnetic field.

The precision sensor provides low offset, low noise measurement

The unique feedback configuration provides accurate and stable gain.

Input and output overload conditions are detected by error flags.

Compensation

Coil

Sense Coil

Magnetic Field inside Bus Bar Hole

46

Field gradient inside the hole is proportional to the current

through busbar

The gradient is measured by two DRV425 sensors on the

opposite sides of a PCB

Common mode fields are rejected

DRV425 - Value for High-Current Measurements

47

Sensor integrated into the BusBar for isolated measurement up to 1000s of Amps

Differential measurement inside the bus bar further increases immunity to stray fields and to frequency effects and to overcurrent

conditions

Lower power than shunt based solutions

Compact module design and ease of installation

High SNR by replacing discrete hall sensors

High accuracy over a wide dynamic range

Lower complexity and single temperature calibration
